Configure pgAdmin for OAuth 2.0

I have deployed pgadmin in an openshift azure cluster

Not thru operator. I am doing this as a POC for my Org

I have deployed this in a separate namespace pgadmin and trying to deploy a single instance 

I want to enable oauth2 authentication 

Using azure ad 

I have followed your documentation 

But I am not able to see oauth login button 

I am using configmap yaml to edit config_local.py

I could see this file present in /etc/pgadmin 

But in oc logs I didn’t see  any logs to if this taken or not

In pod etc/pgadmin I did not see any configfile

Please guide me to verify my configuration 

Thanks
