Decompile from bytecode went wrong

Describe your question in detail.

I'm trying to interact with a lending protocol on-chain but it doesn't reveal the source code. I have downloaded its bytecode and tried to decompile it with the guidance of this tutorial. However, the decompiler seems didn't work well as it doesn't decompile the friend logic.

I don't know any solution beside manually adding friend to the original source code (though I haven't tried because that may cause error when publishing?)

Can anyone please help me?
