Allert with trigger

[Lemroma]

Good evening, is there a way to create a trigger to notify some users if a set of tables is not modified? In detail I have to remind some users via notification to carry out readings to be integrated on the appsheet.

Via an scheduled event

Good morning, thanks for reply. I tried but without success, my request is only to activate a notification to remind the operator to make a data entry. Or does it only work if there are conditions?

this is the error...
