Switching tabs while using Zoom on IPad

Hello Everyone! 

So I have an exam coming up that requires us to keep our video turned on zoom. But in order to take the exam we have to switch tabs. I recently got the IPad Pro, and realized that you when you switch tabs, it pauses zoom video. I was wondering if there is a way around it? 

This is very important to me so any help is very much appreciated. 

Thank you!
