pyqtgraph - how to render object that has a face with more than 3 vertices?

Question

How can I use pyqtgraph to render an object that has a face with more than 3 vertices? The function provided here https://pyqtgraph.readthedocs.io/en/latest/3dgraphics/meshdata.html only allows a face with 3 vertices.

But this is my obj file
