I am creating an app that allows a user to video call another user from a list online users. I am wondering if this is possible with Zoom. The user already creates an account using firebase so I was hoping that I could use the API functions to have the user call another user without having to make a Zoom account in addition to the account they made for the app. I have already implemented a function to join a meeting, but from looking through the API documentation, I could not find any information on a non-login/API user calling another non-login/API user. Any help would be very appreciated!
