Trigger for Text Entry to Play Screen Recording Action

I am working on a simulation in which I need the screen recording action to play when a specific number is entered into a text entry field. I don't want the user to have to click anywhere else, as the screen recording shows a dropdown populating from the text entry field. I cannot use the "When the user clicks" trigger because the text entry ends in 3 and there are 2 other 3s in the number.
