Lua filter for admonition syntax to awesomebox package LaTeX conversion

[mygithubdevaccount]

I would like to write a Lua filter that uses this admonition syntax:

!!! note Consider this
    Consider doing **this** and *this*, but not this.

    ```java
    public class HelloWorld {
      public static void main(String[] args) {
        System.out.println("Hello, World!");
      }
    }
    ```

    This paragraph continues here...

This is a separate paragraph.

and transforms it into this LaTeX syntax. (\usepackage{awesomebox} is declared in a header file):

\begin{noteblock}
\textbf{Consider this}

Consider doing \textbf{this} and \emph{this}, but not this.

\begin{Shaded}
\begin{Highlighting}[]
\KeywordTok{public} \KeywordTok{class}\NormalTok{ HelloWorld }\OperatorTok{\{}
  \KeywordTok{public} \DataTypeTok{static} \DataTypeTok{void} \FunctionTok{main}\OperatorTok{(}\BuiltInTok{String}\OperatorTok{[]}\NormalTok{ args}\OperatorTok{)} \OperatorTok{\{}
    \BuiltInTok{System}\OperatorTok{.}\FunctionTok{out}\OperatorTok{.}\FunctionTok{println}\OperatorTok{(}\StringTok{"Hello, World!"}\OperatorTok{);}
  \OperatorTok{\}}
\OperatorTok{\}}
\end{Highlighting}
\end{Shaded}

This paragraph continues here\ldots{}
\end{noteblock}

This is a separate paragraph.

If rendered correctly in LaTeX it would look like this:

I have written a basic Lua filter for this (please exucuse my bad Lua skills, also this needs refactoring):

-- parses a paragraph
function Para(paragraph)
  if paragraph.content[1].text == '!!!' then
    print("Paragraph starts with '!!!'")
    if paragraph.content[2].tag == 'Space' then
      print("Paragraph follows '!!!' with a space")
      if paragraph.content[3].tag == 'Str' then
        local admonition_type = paragraph.content[3].text
        print(admonition_type)
        if paragraph.content[4].tag == 'Space' then
          print("Admonition type followed by a space")

          local heading = ""
          i = 5
          while paragraph.content[i] and paragraph.content[i].tag ~= 'SoftBreak' do
            token = paragraph.content[i]
            if token.tag == 'Str' then
              heading = heading .. paragraph.content[i].text
            elseif token.tag == 'Space' then
              heading = heading .. " "
            elseif token.tag == 'Quoted' then
              heading = heading .. pandoc.utils.stringify(token.content)
            end
            i = i + 1
          end
          print(heading)

          body = ""
          if paragraph.content[i] and paragraph.content[i].tag == 'SoftBreak' then
            body = pandoc.List({table.unpack(paragraph.content, i+1)})
          else
            body = '' -- no body
          end
          print(body)

          local awesomeblock_begin = '\\begin{' .. admonition_type .. 'block} '
          local awesomeblock_end   = '\\end{'   .. admonition_type .. 'block} '
          return {
            pandoc.RawInline('latex',
              awesomeblock_begin .. '\\textbf{' .. pandoc.utils.stringify(heading) .. '}' .. '\n\n' .. pandoc.utils.stringify(body) .. awesomeblock_end)
          }
        end
      end
    end
  end
end

This does it basically, but it only captures the heading and the first paragraph content. I cannot get the Java source code block and the next paragraph. These are identically indented with 4 spaces, i.e. the whole admonition block is indented with 4 spaces.

How to capture the following paragraphs and render it like above? Is this even possible in a Lua filter because I would need to check whether the following paragraphs are indented with 4 spaces?

Interestingly this is basically the Bullet List semantics:

- **Consider this**

  Consider doing **this** and *this*, but not this.

  ```java
  public class HelloWorld {
    public static void main(String[] args) {
      System.out.println("Hello, World!");
    }
  }
    ```

  This paragraph continues here...

This is a separate paragraph.

renders similarily:

If I only could convert the custom block that starts with !!! into a block with list semantics.

I've switched to Div syntax (::: note) instead of !!! note, so I dont need an answer here anymore. It would be nice to have an official syntax extension for admonitions, but there are several ways to create admonition blocks. Using Div syntax and a Lua filter creates the most versatile boxes with tcolorbox.
