unity admob + firebase remote config issue : admob mediation error

Question

I have implemented admob and firebase (analytics, messaging, firestore) in unity all are working well. Later I added a remote config of firebase and even it's working well. But now when I request any ads like banner, rewarded, it's throws error :

E/Unity: AndroidJavaException: java.lang.ClassNotFoundException: com.google.android.gms.ads.mediation.admob.AdMobExtras

I have removed remote config sdk from unity but still is throws error. I would be thankful if anyone can help me out.

VERSION USED

Unity 2021.2.13f1 | Admob v7.0.0 | Firebase 8.10.0

I Solved this by changing this line into GoogleMobileAdsDependencies.xml

<androidPackage spec="com.google.android.gms:play-services-ads:20.6.0">

to this line

<androidPackage spec="com.google.android.gms:play-services-ads:[20.6.0]">
