[Question]: how to tell when Onesignal.Notifications.requestPermission() fails?

[ggrochow-dh]

How can we help?

Assuming I have blocked browser notification permission for the site I am doing this on.

when calling Onesignal.Notifications.requestPermission() I see an error output in the console, but get 0 feedback from the function call, and im unable to catch the error.

How can I tell when this has failed? I want to be able to instruct the user they have to manually change their browser settings, but it seems like there is no way to get any feedback around this very critical part of this whole process not working.
