¿como ocultar una accion por tiempo y sesion programada?

I am new to appsheet and I have the following question:
How to enable an action by time and scheduled session?
The scheduling of the event is done with Calendar and the survey is referenced by the name of the session.

Thanks in advance

In Behavior >> Actions in the app editor, each action has an Only if this condition is true setting. There, you can enter an expression that evaluates as TRUE only when you want the action to be available. You can construct an expression that consults the calendar table and any other data that is available in the app.
