  <p>As mentioned in the <strong>picture a</strong>,  we need to use new google account to create test manager account that is not been used in production manager account, I did the same. I created new google account and created test manager account but when I try to generate Refresh token for test account by using OAuth playground, It generates an error. see picture b.</p>

  <p>Am I doing something wrong to configure the test manager account? Is there anything I need to follow to enable test account? The request to generate refresh token is getting denied. Is it because my account is closed?</p>
