Is there a way to trigger notification for first time only?

Hi folks,
is there a way to trigger notification only for the first time to notify to invite the user to the APP and once they are in the APP, notifications stop?
thanks

If you add a checkbox to the user “Invited?” and change that to true the first time the action workflow runs, then change the workflow so it only runs if “Invited?” is false, it will only run once.

Thanks
Can you please elaborate on this one!
Appreciated.
