Minimal Scaffold with EF does not work when `DbContext` declared in an external library

I have a very simple DBContext:

public class SampleModel
{
    public int Id { get; set; }
}

public class SampleModelContext : DbContext
{
    public DbSet<SampleModel> Samples => Set<SampleModel>();

    public SampleModelContext(DbContextOptions<SampleModelContext> options)
        : base(options)
    {   }
}

That I have configured in my Minimal API application:

using Microsoft.EntityFrameworkCore;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddDbContext<SampleModelContext>(options
    => _ = options.UseSqlServer(builder.Configuration.GetConnectionString("SampleDB") ??
    throw new InvalidOperationException("Connection string 'SampleDB' not found.")));

var app = builder.Build();

app.Run();

I can scaffold without problems If the SampleModel is part of my Minimal API assembly, however, when moving it to a new assembly I start getting:
