There's this AFK Matchmaking app which I tried about a year ago. It worked but it was a hassle to set up every time you queued.
Something where it would automatically come up on your phone if your phone wasn't near your computer would be amazing. Also to notify when pick phase starts, and when pregame starts.
Isn't there an app for it already? I'm not sure if it is this one.
This has been done before: https://play.google.com/store/apps/details?id=com.itsalive.afkmatchmakingfree&hl=en
But it seems like his website is not maintained anymore, and I'm not sure if he took down his server. You can also consult his client repo on github: https://github.com/fareesh/AFKMatchmaking. If you look at his approach he used mouse_event to click on the accept button. Also, he sets up hook to listen to window events instead of looking at audio to see if the queue popped.

Is this what you are talking about?
I used to use this app, but i'm not sure if it still works. Kinda neat i would say.
