A way to implement IdP broker using keycloak

I have a use case where I need to integrate the 3’rd part IdP originating from the customer organization. This allows the customer to provide permissions to his personal and control it via his IT department. Some customers may be using SAML and some OIDC. is there a way for keycloak to be used as some kind of bridge here? I’ve heard the phrase IdP broker, org2org by OKTA. I would really rather use an open-source tool here.
