❔ Tph strategy and fluent api. How to specify that a property of child class is required

Hi, I am trying to set column of my child entity Product required. Product is a child of Owned class. But the constraint in not applyed. I can using SSMS insert without specify a value. Below my code :

protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            modelBuilder.Entity<Owned>()
                .UseTphMappingStrategy();
            modelBuilder.Entity<Owned>()
                .HasDiscriminator(o => o.Descriminator)
                .HasValue<Product>((int)OwnedDescriminator.Product);
            modelBuilder.Entity<Owned>()
                .HasKey(ow => ow.Id);
            modelBuilder.Entity<Owned>()
                .Property(ow => ow.Id).IsRequired();
            modelBuilder.Entity<Owned>()
                .Property(ow => ow.Name).IsRequired();
             modelBuilder.Entity<Product>()
                .HasBaseType<Owned>();
             modelBuilder.Entity<Product>()
                .Property(pr => pr.Sku).IsRequired(); // TODO TEST with true SQL SERVER
            modelBuilder.Entity<Product>()
                .Property(pr => pr.PriceSell).IsRequired(); // TODO TEST with true SQL SERVER
}

protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            modelBuilder.Entity<Owned>()
                .UseTphMappingStrategy();
            modelBuilder.Entity<Owned>()
                .HasDiscriminator(o => o.Descriminator)
                .HasValue<Product>((int)OwnedDescriminator.Product);
            modelBuilder.Entity<Owned>()
                .HasKey(ow => ow.Id);
            modelBuilder.Entity<Owned>()
                .Property(ow => ow.Id).IsRequired();
            modelBuilder.Entity<Owned>()
                .Property(ow => ow.Name).IsRequired();
             modelBuilder.Entity<Product>()
                .HasBaseType<Owned>();
             modelBuilder.Entity<Product>()
                .Property(pr => pr.Sku).IsRequired(); // TODO TEST with true SQL SERVER
            modelBuilder.Entity<Product>()
                .Property(pr => pr.PriceSell).IsRequired(); // TODO TEST with true SQL SERVER
}
