Z-Index & Button display issues

Z-Index & Button display issues

I've been trying to add a button (which opens a sidebar) to my site but have been running into trouble.  The form & button code (below) comes from Typeform.

I have tried entering it as a code snippet on an individual page but nothing displays
Entering it as footer code displays nothing
Entering it into the header code gets the button to show but it is hidden behind every other element on the page.

The Typeform dev has said that the Z-index of their widget is 10001, the code below says its 9999.  But either way, I've tried increasing the below Z-Index code but both the button and the form still get hidden behind the rest of the elements on the page.

Can anyone see why this may be happening or maybe how I can alter the z-index of the rest of the site to try that method?

Site is https://www.efinancial.education and I'd need the button to display on every page as its my main CTA for the site
