Qorovo Nearby Interaction SDK

Hi all:
I have a few questions I’d like your help with.
1.At present, qorvo has an Nearby Interaction SDK based on noridc series chips. Is there an sdk for silabs(EFR32BG22xx chip)?
2. If i port the current Nearby Interaction SDK to silabs,how to operate, is there any specific documentation?

Best wish
