Blazor - navigate to different project component

Hi.

I would like to create multiple blazor projects. Example:

documentation.domain.com
tasks.domain.com
process.domain.com
authentication.domain.com

I have authentication enabled and I wish to redirect all of these different projects to the authentication.domain.com/login Blazor Component when the user is not logged on.

Could you kindly give me some hints.

Regards,

Chris

What I have tried:

I am running IIS Express and using Navigation Manager.

I know I should use Naviagtion Manager to navigate, but I cannot think how I should be able to navigate to it.
