Are Local Notifications supported in a PWA?

Before I spend too much more time trying to get my PWA to show Local Notifications, I thought I just should ask if they are actually supported.

In my PWA, I have a ion-button that when clicked calls LocalNotifications.requestPermissions(); but through Chrome DevTools I can see that an error is thrown:

ERROR Error: Uncaught (in promise): Error: Notifications not supported in this browser.

This is on my Android phone.

Here is my info:

$ ionic info

   NodeJS : v12.19.0 (/usr/local/bin/node)

according to this issue, Notification API (that local-notifications plugin uses) is not supported on Android PWA
