Do you know where I can find 'all the Twitter-IDs that belong to ''Offices'' (like @POTUS & @VP)?

Tweet

Ever since Twitter started, the I.D.s @POTUS & @VP have been held by 'whoever held that office,' haven't they? (I'm just guessing, since '@POTUS' has been Bush 2, Obama, Trump & now Biden) ... maybe 'famous media company-I.D.s (like @CNN, @MSNBC, @FOXNEWS, @NEWSCORP etc.) I look for a list of them, but I can't generalize my search-terms enough to make Microsoft Bing think I'm looking for 'a list of such Twitter-I.D.s' (like @Microsoft & @Bing). The closest I could find was an article about 'how @POTUS (also @VP, @PressSec, @WhiteHouse & @FLOTUS) was passed from Obama to Trump in 2017.' https://www.washingtonpost.com/news/the-intersect/wp/2017/01/20/so-what-happens-to-the-potus-twitter-account-now/ What IDs do you think will be useful 'forever' like that?
