@Arthanareeswara,
Lets review a few things.
1) You've got a subscription (free or otherwise) to Google G Suite?
2) You've enabled the GMail API in your Google console?
3) You've created a service account in the Google console under "APIs & Credentials"?
4) You've added the service account details (email address and private key) to a OAuth 2.0 (JWT Bearer Token) credential in Blue Prism?
5) You've associated that credential with the Google GMail Web API definition in Blue Prism and updated the Common Authentication details as mentioned previously?
Cheers,
