Hey Rishabh,

I did the same as you said but I am still facing the same issue.
Any specific role is required for Service account email id or user email id?

Hello,
Now I am able to use Gsuite Gmail Activity using Service Account.

Steps:

1. Create a Service Account.

2. Enable Domain Wide Access to the Service Account
   and

3. Provide Authorization to the Service Account:
   액세스 사용자 인증 정보 만들기  |  Google Workspace for Developers  |  Google Developers

4. I have also added the below scope in OAuth Content Screen as shown below:
   

   

So this is working fine for me. Hope it would help you.
