Making smart glasses using Arduino

Question

I am trying to make smartglasses for a school project. I planned on using the RetroWatch app but it is no longer available in the playstore. Does anyone have any suggestions for other ways to allow the bluetooth to get notification data from the phone?

I followed the tutorial here https://create.arduino.cc/projecthub/rev_atomic/augmented-glasses-a9db7d?ref=part&ref_id=11332&offset=1 but it doesn't cover how to allow the android to send notification data
