Switching between multiple cameras in Zoom

I have 5 Webcams in a meeting room connected to Zoom which I switch between as different people speak.

I used an app recommended in the OBS forum to give  each camera a sensible name which helps.

I simply use the camera selection option (via the menu you access from the arrow next to the video button) to switch between cameras.

Howver, ideally I woudl like to be able assign each camera to a hot key (e.g. Camera 1 on F1; Camera 2 on F2 etc.) I can see that there is an OBS solution, but the PC which I am using is not powerful enough to do that.

Is there anyway that this can be achived? Is there a Macro which could be used?

Thanks
