Integrating Keycloak in Micro Frontends with Single SPA and Angular

Question

I'm new to micro frontends and I'm currently building an application using Single SPA, where the child applications are written in Angular 16. I'm now at the stage where I need to integrate Keycloak authentication into my micro frontend architecture.

My question is: should I incorporate Keycloak directly into the Single SPA root configuration, or should I create a separate app just to handle Keycloak authentication?
