Facing issues with Push notification icon and sound (even with notification click) in Android version < 12

[Nykz]

What happened?

Onesignal push notification works fine in android 12 and above perfectly but in versions less than that the following problems are faced:

1. Notification small icon not displayed instead a blank gray background shows up. Large icon shows properly
2. Notification sound is not played until permission is given from settings
3. When click on notification, opened is not opened if closed. It only opens up, if you have another app opened and then you click on the notification. When i click when no app opened it doesnot open at all.

Tested it in Android 9 Redmi Note 5 pro & Android 11 Redmi Note 8 pro
