ACCES

If by "authorization" you mean manually admitting people to your meeting from the waiting room, I suggest you turn off the waiting room and set up a meeting password since Zoom requires users to enable at least one security option in most cases. Then, all you have to do is provide participants with the meeting ID and password, and they can join your meeting directly after entering the correct information. You can find the settings under Settings > Meeting > Security in your Zoom web portal. 

If your attendance in the given meetings is part of the issue, I'd also recommend enabling the "allow participants to join before host" feature:
