Not sure which two panels and what differences you’re referring to. Please elaborate.
We had a discussion about this with your colleague here Is there an interface for next page of Float Video? and here Seeking floating panel interfaces and here Is there an interface for next page of Float Video?
While he mentioned the correct interface and while some of the interfaces were added in the mean time they don’t work as intended! Again please refer to the original zoom client and take note that when you’re in a meeting with a bunch of participants the floating panel with appear on the right hand side and all the floating panel interfaces work whether someone is sharing or not.
