Chat Bot embed behind content

Design help Custom code

I can’t get this right. I want to embed a chatbot and it keeps behind my content no matter what readonly link I provide or z-index I add (I added 9999).

Here is the page I want it embeded on.

I kind of got it to work on my home page but only sits above some content:
