In the 'Integration' section of an OpenID Connect configured service, the "Authentication Settings" configuration specifies an OIDC issuer endpoint. The placeholder text set as

https://sso.example.com/auth/realms/gateway

This is misleading as the correct format is:

https://<CLIENT_ID>:<CLIENT_SECRET>@<HOST>:<PORT>/auth/realms/<REALM_NAME>

Suggestion: Update the placeholder text to be more inline with correct format.
