Unfortunately, that is not possible. You can temporarily unsubscribe and deactivate all email notifications in advance in the settings. However, other users will not see this and you will still be invited.

There is a little trick: change your location to, for example, Paris. There are no meetings and no users - you will usually not be suggested to other users and will not be invited by anyone.

To change the location, tap on the location icon in the meeting overview (the small pin in the top left corner) or on your city under the "meet5".
