Hi,
HoloLens is currently not supported in the Q&A forums, the supported products are listed over here https://zcusa.951200.xyz/en-us/answers/products (more to be added later on).
You can ask the experts in the dedicated HoloLens forum over here:

or you can also ask directly in the dedicated HoloLens Slack channel:

Best regards,
Leon
