Zoom with obs

[camochick]

I would like to add guest joining (not talking) just showin up, one after the other maybe a 20 sec each then switch to another person during obs live. This might be done with zoom... or maybe another app I don’t know. if you can take a look at the link you’ll better understand what i’m trying to do. https://youtu.be/hE_apx2B0uQ
Thank you for the help or idea you can provide
