Dynamically configure Keycloak realm

[Snotax]

Is your feature request related to a problem? Please describe.
We have a multi tenant application where one realm equals one tenant.

Describe the solution you'd like
I would like to know if there is a possibility to support / implement a dynamic realm selection with your library.

Describe alternatives you've considered
I tried replacing the realm and client config of the keycloak instance, but that creates more problem later with refreshing etc(as you probably know).

Additional context

• Have you ever encountered a similar problem / request before ?
• We have the realm information in a query param
