@yellow_fleurs: I use VSee too. There are actually two VSee apps -- VSee (the original) and "VSee Clinic."

The Clinic app has a "waiting room" feature where you log in and your pdoc/therapist clicks your name to start a call. (It's basically like a regular chatroom, except instead of clicking someone's name to type a message to them, you click the person to start a video or voice call. But if you're a patient in the waiting room, you cannot see other patients who are "waiting" there. Only your provider can see who's there.)

The regular VSee app has no such "waiting room" feature. Your pdoc/therapist has to know your email address in advance, they send a request for you to add them as a "friend," and THEN they can call you and you have to pick up the phone. It requires more setup and isn't as user friendly as the "Clinic" version.

Both apps allow you to disable the video if you want. There are buttons that show up on your phone screen that you can press. For example, here's a screenshot from my phone:
