Shuffle between screens (monitors)

I am unable to shuffle between two screen on two different monitors while recording. One one screen I want to demo a web app and then in between I want to switch to a Google slide which is in a different tab on a different monitor but I am not able to record the second screen (Google slide) even when I move the mouse to the second screen. Not entirely sure if it was working previously. I can shuffle and switch before I start the recording but in midst of the recording.
