I have a personal Google account. I can create Google Meet rooms easily by clicking on the "Start a meeting" button:
The URLs created by clicking that button are like https://meet.google.com/xxx-yyyy-zzz. The problem is, it seems it is not possible to create a room with an arbitrary xxx-yyyy-zzz (see this example).
So, I am guessing, in order to create a new room/URL for a meeting, you need to use the "Start a meeting" button.
The thing is, I would like to use the same URL/link for meetings with someone in the future (i.e.: I would like to bookmark it and reuse it anytime I want to talk to that person). I wonder if the link will still be valid then.
What is the duration of that link/URL? Do I need to revisit the URL from time to time in order to avoid expiration?
