Use a the built in Wait option inside a useless 'Send mouse click':

It seems as though processing the action itself takes roughly 0.2 seconds, so I set the Wait of the click to 300/1000 of a second.
I put two of these back to back, and my timer Play/Pause button was at the coordinates listed:

So, if it takes .2 to process an action, you might have to play with it a little bit, but I would start with a 100 Wait here. That's 200/1000 to process the mouse click action + 100/1000 for the wait inside the mouse click action + 200/1000 to process the action you were trying to wait for.
Best of luck!
