Android WebView push notification?

I need to send a notification (not necessarily a push notification) through an android webview. I saw that the Notification API was not compatible with Android Webview on MDN. The other APIs I saw seemed to be based off of window.notification.

Does anyone know of any API or JS that sends a notification through an android webview?

I saw this post from 6 months ago with essentially no activity except a vague mention of firebase. Would that be helpful?

Thanks for your answers!
