Hey, ​@Ali alzubaidy 

It’s not possible to set a timer for your action’s buttons.

But there is a tricky way to that, and it’s a boooooooring thing to do  

First - you have to create a user field like {current time} with date/time.

Second - before all of your buttons, you have to create an action block to set the user field {current time} to the date/time of the action.

Third - after all of your buttons, you have to create a condition block that “says” (example): If an hour has passed - do nothing, but if it’s not been an hour, send the message.

I hope this helps and good luck (and patience )
