How to always make a code snippet from another microfrontend to run regardless of route

[GZLiew]

Hi single-spa

thanks for for the great library

we have a container app microservice which will load other microservices from the route config

but we have a auth microservice which has an user session checker/manager code that needs to be run globally regardless of which route is loaded to the container app

we want a separation of concern where the container root app just loads code given by other microservices
(something like a hook child microservices can define)

I hope I can get a few advices

thanks
