How to use AddIdentityApiEndpoints inside a class library?

Question

I have separated my identity code into a dedicated class library. I have an IServiceCollection extension method for adding everything I need except this one line:

builder.Services.AddIdentityApiEndpoints<IdentityUser>()
    .AddEntityFrameworkStores<ApplicationDbContext>();

No matter which package I include, AddIdentityApiEndpoints is never recognized. What do I need to do to be able to use AddIdentityApiEndpoints from within a class library?

The documentation page's "Definition" section is terse, but it essentially says that you need to have:

• a <FrameworkReference> to Microsoft.AspNetCore.App.Ref in your .csproj.
• a <PackageReference> to Microsoft.Extensions.Identity.Core in your .csproj.
• a using Microsoft.Extensions.DependencyInjection namespace import in your Startup.cs
