Allow and deny users after sign in from google sso

I have integrated google sso with grafana. I want to achieve this -

  1. There should be something like after user login into grafana from google sign in. There must be something particular user should be allow or deny
  2. There must something where can mention list of users which can admin access, editor access and viewer access in conf file. I should go into manually into console and change access level.

I refer this charts for deployment -

Version -
grafana-server -v
Version 9.0.1
