JavaScript Experts help me

This is very urgent job, must finish today.
Only experts bid on it, please

This page isn't ours and the have implemented the setTimeout code.

so all interaction on this page happens in the tabunder, which is not visible to the user. and the domain is not ours. it's a partner website where we want to:
1. accept the cookie consent
2. start the video and play the video ads
3. mute the video
4. show users in google analytics tracking

and this all under the condition that the user actively doesn't focus the tab

Js experts will get a sense with description, if yes, please send me message
