My init params:

          const gauthOption = {
            clientId: this.getConfig['social-networks']['google-client-id'],
            scope: 'profile email https://www.googleapis.com/auth/user.birthday.read',
            prompt: 'select_account',
            ux_mode: 'redirect',
            redirect_uri: `${this.siteUrl}/social-login`,
            response_type: 'token',
          }

I expect that the callback url after successful authorization will contain an access_token, but it contains an id_token. Maybe this can be fixed by changing the 'scope' or 'response_type' values?
