There's a lot more to it than just an embed type

I was looking about the embed fields of type "poll_result", then I decided to use the getMessage method, and apparently, it already returns an array of embeds with the corresponding fields 🤔

[
  { inline: false, name: 'poll_question_text', value: 'test' },
  { inline: false, name: 'victor_answer_votes', value: '1' },
  { inline: false, name: 'total_votes', value: '1' },
  { inline: false, name: 'victor_answer_id', value: '1' },
  { inline: false, name: 'victor_answer_text', value: '1' }
]

So, that's why I decided to add only that type of embed 😅

You can try to get a message of that type and you will see that it will possibly return an embed of type "poll_result"
