Identify the text area of the response

[Orkessler]

In the current code, we recognize the text field in the responses only in the following situations:

   const twitterTextArea = document.querySelector('[data-testid="tweetTextarea_0"]');
   const facebookTextArea = document.querySelector('[aria-label="comment writing"]') || document.querySelector('[aria-label="Write a comment"]');
   const instagramTextArea = document.querySelector('[aria-label="Add a comment..."]');
   const existingTextArea = twitterTextArea || facebookTextArea || instagramTextArea;

There are users who complain (especially on Facebook) that the auto-fill in the response area doesn't work for them.
All options must be covered for all users...
