Adding Live Chat on mobile and desktop if there is a sticky bar at the bottom?

Typically, live chat is located on the bottom right as a floater either on desktop and mobile. However, on some of my pages, I have a sticky bar with a CTA button on the bottom right. If we were to add a live chat, the live chat would cover the CTA button.

If we move the floater above the CTA button, it would cover some of the information on the side...

Additionally, is it best practice to keep desktop and mobile experience the same? I think I might need to make the live chat experience different from the mobile site.

I need help figuring out the best place to put a live chat function on this page. Help please!
