Network Slicing on IOS 17,or later.

For the 5G Network Slicing Traffic Category defined by the IOS 17: https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_developer_networking_slicing_trafficcategory?changes=latest_major&language=ob_8

May I know more details, better with providing me the reference link, on the following questions,

1. How this ID is being handled by the network?
2. What’s the flow & impact of this ID when registering the 5G SA network?
3. Any profile is being downloaded from the network to the handheld device to control the slice??
4. That ID is carry along the way up to the BBU/Cell sites and the ID is identified by the cell sites for specific handling of that slice?
