❔ Substitute interface property?

I have this interface:

public interface IAzureBlobStorage
{
    UsersContext Users { get; }
}

public interface IAzureBlobStorage
{
    UsersContext Users { get; }
}

And i'm trying to do some method chaining. But .Users is NULL, substitute doesnt overwrite that.

  var azureBlobStorage = Substitute.For<IAzureBlobStorage>();

  azureBlobStorage
      .Users
      .WithId(Arg.Any<Guid>())
      .GetProfileImageOrDefault()
      .Returns(Substitute.For<BlobClient>());

  var azureBlobStorage = Substitute.For<IAzureBlobStorage>();

  azureBlobStorage
      .Users
      .WithId(Arg.Any<Guid>())
      .GetProfileImageOrDefault()
      .Returns(Substitute.For<BlobClient>());

Any way i can make this work with NSubstitute?

it wasnt Azure specific, i was just mocking the interface, which is a wrapper to azure blob storage making everything an interface worked
