My Question

I am developing an integrated application based on PySide6, and I need to display some point cloud information with text labels. The old Visualizer cannot directly add labels, and I cannot find a way to integration the new O3DVisualizer.
So I'm asking for a sample to integration the O3DVisualizer.
