If you can embed HTML you can also embed JS inside HTML. I’m not sure what you want to do but if you are not using Velo and you need vanilla JS for some reasons you can do it by adding your JS code inside <script> </script> tags in your HTML embed.
Thanks again for the reply.
I’m adding the JS with the embed HTML in the elements section.
It has <script type=text/javascript and the beginning and it closes with </script
What do you want to do with JS maybe it’s not possible or maybe there are some other solutions to what you are trying to do. If you can add more context about what are you trying to do by embeding JS I can help you better.
