If you join a meeting with the Zoom Client you have to insert ID and passcode, always! There is no way to avoid it.
The recent meetings list is usefull becasue you have to put only the passcode, the ID remains saved in the Zoom Client. If you delete the list the next time you need to join the meeting you will have to put ID and passocode... What's the advantege of deleting the list?e
If you have the link to join the meeting: you can copy it in your browser (and save it in your list of favourites) and then chose to open the link with your Zoom app. So you will not need to insert neither the ID number nor the passcode.
