unable to join s meeting

I received advice that a friend wanted to schedule a Zoom meeting with me [on my Apple desk top computer] I  said ok and they sent me a meeting ID and timing details    I accepted these and waited but was not invited to join the meeting   It could be that my old Apple device was not up to it.

I would like for someone to invite me to a hypothetical meeting so that I can go through the process again  Trying to check what went wrong.  Would have liked Zoom support to do this but it is impossible to get this request answered
