I found a solution for now. Adalo support confirmed this is not possible.
I was able to get around the issue for now by using the countdown element (made invisible) and run the custom action once the countdown is complete, then it updates the the database. I wasn’t able to do it on a “previous” page because it’s the home page and the user would be getting there from a Push-Notification. (Since we can’t direct users to specific pages from a push notification).
