@sheilamjones , here I am sending some suggestions that I could add directly to your PR.

1. Line 178: (missing comma)
   The quarkus.oidc.client-id property references the client_id issued by the OIDC provider, and the quarkus.oidc.credentials.secret property sets the client secret.

2. Line 180: (minimalism/grammar)
   The quarkus.oidc.application-type property is set to web-app to tell Quarkus that you want to enable the OIDC authorization code flow so your users are redirected to the OIDC provider to authenticate.
