How generate a patch object with tetramesh?

I have a triangulation object and I'm trying to create a patch from it using tetramesh, but once I use tetramesh it gives me double instead of patch. How can I get a patch from triangulation that is meshed with tetrahydrons?

         d = [-1 1];
        [x,y,z] = meshgrid(d,d,d);  % A cube
        x = [x(:);0];
        y = [y(:);0];
        z = [z(:);0];    % [x,y,z] are corners of a cube plus the center.
        dt = delaunayTriangulation(x,y,z);
        Tes = dt(:,:);
        X = [x(:) y(:) z(:)];
        h = tetramesh(Tes,X);camorbit(20,0);

        
        size(h)

ans = 1×2

1 12

        class(h)

ans = 'matlab.graphics.primitive.Patch'

        h(1)

ans = 
  Patch with properties:

    FaceColor: 'flat'
    FaceAlpha: 0.9000
    EdgeColor: [0 0 0]
    LineStyle: '-'
        Faces: [4×3 double]
     Vertices: [12×3 double]

  Show all properties

Doesn't look like a double to me...

which release is yours?

R2020b.

In R2020a and earlier:

Record the vector returned by tetramesh(), and call handle() on it. The result you get back will be a patch array.

In R2020b, the value returned is a patch array directly.
