how to use ONNX for multi mask?

How to get all the masks from the image using onnx, the notebook implementation is for a single mask. Help is appreciated

Start by reviewing the repository's example notebook implementation and the ONNX inference path to understand how the single-mask result is produced. Determine whether multi-mask output is supported and document or demonstrate the required usage; done means the process for obtaining all masks is clear and reproducible.
