Hi there! Thanks for taking the time to PR this - that is certainly unexpected though, do you have any documentation or upstream links for it? I believe you and am inclined to merge but this wasn't noted anywhere and it apparently doesn't have any test coverage so I don't have any way to verify it

[yunarta]

Hi mike

according to this doc https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/generating_a_remote_notification

the badge count for ios is not within alert, but it is at the same level as alert.
as this is a push notification function, it would be hard to create test and coverage over it, hence i didnt do any of it.

[mikehardy]

Yes the test cover here is really hard, but the docs link is great, thank you!

LGTM - seems to correlate with where the docs say the badging information is - thanks @yunarta !
