OpenID with Google is failing

I have a OAuth2.0 set up with Google as authorisation provider and it is working fine. Now I am trying to add openId piece to it and it is throwing 401 error.

 

I am not even sure whether I have done all the necessary extra steps for OpenId as I could not find any document for that.

 

Can anyone please point me to any document which explains OpenID and JWT tokens with F5 as Client and Resource SErver and Google/Facebook as authorisation providers.

 

Thank you
