How to use DbContextFactory with multi-tenancy in Blazor Server?

I have a multi-tenant Blazor Server App. Multitenancy is handled by Finbuckle.Multitenant.

I set up my tenant info based on the following article.

Currently, in my Startup.cs I have the following:

services.AddDbContextFactory<AppContext>(options =>{    options.UseSqlServer(configuration.GetConnectionString("App"));});

However, I need to change this so that the DbContextFactory is registered with the DI after the app starts and the tenant is known.

Is this possible? How can I do this?
