Tessa, I don’t know the specific answer to your question (you can experiment), but the main problem is that the “PWD=” argument in the meeting link URL is NOT the password, but a value computed from the password. In this thread I have been arguing with Zoom about this user-unfriendly design and their response above is that they will not change it.
So, currently, you cannot change a meeting ID and password into a URL to bookmark it or create a command from it. That was Zoom’s conscious and stupid decision and it will stand perhaps until another company captures the enormous Zoom market by offering more flexibility, more convenience, and less arrogance toward users.
