Probuilder API mesh transform and vertices

I'm trying to move my newly created plane shape to a specific location.
I would like to move my 1x1 plane generated by ShapeGenerator and place the mesh at some specific position for e.x. vector3(3,0,3).

If I do it like that

ProBuilderMesh mesh = ShapeGenerator.GeneratePlane(PivotLocation.FirstVertex, 1, 1, 0, 0, Axis.Up)

mesh.transform.positon = new Vector3(3, 0 ,3);

It moves the mesh to the position but IT DOESN't moves the vertices of the mesh.

How I can translate the vertices so they math the object position??
