How do I give a user admin rights when I am using delegated authentication and cannot log into the admin console?

Issue 
 
 I am trying to log into the admin console, but cannot log in with the provided onprem-admin-donotdelete user as I am using delegated authentication. 
 
 Environment 
 
 Element Server Suite 
 
 Resolution 
 If you wish to give @bob:server.name admin access, then as a user with kubernetes access to your environment, run: 
 kubectl exec -n element-onprem -it pods/synapse-postgres-0 -- /usr/bin/psql -d synapse -U synapse_user -c "update users set admin = 1 where name = '@bob:server.name';"
 
 You will want to replace @bob:server.name with the actual user that you wish to give admin to. 
 Root Cause 
 The issue is that the delegated authentication does not have an onprem-admin-donotdelete user and so there is no way to log in with the provided admin account.
