How to add twitter feed to site in studio?

This is -- or should be -- a layup manually, but without the ability to edit the html manual in the IDE, I can't get it to work. Twitter says just add to your site, and you'll get what you want. Somehow I doubt that. All I get is a link in can click on, hardly a box of tweets, and this is after I split of the script part into a JS file because bootstrap studio just isn't having that!

<a href="$$$$?ref_src=twsrc%5Etfw">Tweets by $$$$</a> <script async src="" charset="utf-8"></script> 

I followed the instructions here and had no trouble embedding a Twitter timeline
