unable to add firebase authentication to my app : I've successfully connected to firebase but when i click on "Add Firebase Authentication to your app " and click on accept changes nothing is happening Iam not getting any errors as well as Iam not getting the message "dependecies added succesfully".

I've checked the gradle section of my app and the dependencies are added correctly but iam not getting the green star saying "dependencies added succesfully".


These are the dependencies that have been added to my project

         dependencies {
              classpath 'com.android.tools.build:gradle:3.4.1'
              classpath 'com.google.gms:google-services:4.2.0'
             }[enter image description here][1]
