Adding code to with Glide

I have a (Javascipt) view app that I would like to integrate into Glide. Is this possible in any way?

What is a Javascript view app?

I’m going to assume that if HTML is not recommended, javascript definitely will not be allowed in the app. You could probably link to a website that contains the javascript.

im seeing apps with cool designs which i assumed it was code or a script

Do you have any examples? I think most people are creatively using images as buttons.
