FWIW, the icon for calendar event notifications appears to be that generated from resources/icon.png using ionic resources. Incidentally, on Android the app stops when you select calendar notifications. Not sure if this occurs in the official MM app.

Re: Custom push notification icon using Moodle Airnotifier?
by Paul Sharpe -
From reading https://moodle.org/mod/forum/discuss.php?d=280032 it sounds like the answer is "no", until Moodle's Airnotifier supports custom apps.
Hi Paul,
if you have a custom app, you should use your own Airnotifier instance
