I use hosted Blazor solution based on the Blazor WebAssembly project template.

https://docs.microsoft.com/en-us/aspnet/core/blazor/security/webassembly/hosted-with-identity-server?view=aspnetcore-5.0&tabs=visual-studio

All works great by default

services.AddIdentityServer()
    .AddApiAuthorization<ApplicationUser, ApplicationDbContext>();

But how can I replace ApplicationDbContext with CustomUserStorage?
