Android Question Advertising Id and FirebaseAdMob2

[aeric]

If I want to show mobileads using FirebaseAdMob2, I must also implement Advertising Id?

I need to call GetAdvertisingId in B4XPage_Created?
If No, do I still need to add the following line in manifest editor?

AddPermission(com.google.android.gms.permission.AD_ID)

All the while, I never implemented Advertising Id in my apps which show Admob.
