Keycloak Operator, is the guide correct?

I followed the installation steps in the guide:

Keycloak is running, but I’m not able to access it.
After installing the non-operator version, Keycloak is accessible on port 8080. But this port is not configured in the operator version.

I tried the other 3 ports which are configured (8443, 9090, 8778) but no dashboard appears.

How should I access the dashboard of Keycloak using the Operator installation?
