How to share container's authentication with React Micro Frontends?

I wonder how one could manage Auth0 authentication (lifecycle) with Micro Frontends. I am building a React SPA which has a container that contain other micro-frontends and am considering the PKCE flow. What do you think would be the most effective approach to share the authentication? I think that one approach is to inject the token to micro-frontends by the container (that handles authentication) during initialization and another approach is to share the token via cookies. Also, should I be using Auth0-spa-js or auth0-react?
