Keycloak: Make getBaseUrl public / Add account console URL helper

[psuet]

Keycloak provides some internal services like the account console that would be accessible via

/realms/{realm}/account

Currently there is no easy way to generate such a URL. One must access the base config of the provider or the env values directly.

I would suggest either adding a simple account console helper or making getBaseUrl public so every consumer can generate the URL by itself.

Can you link to the docs please?
