I want to create a hands-free application （e.g. smart lock）using the Nearby Interaction framework. Nearby Interaction sessions can only be active when the app is in the foreground, however, it can't be a complete hands-free application. Does anyone have any good ideas?

By referencing to the Developer Forums, we could handle multiple concurrent sessions using iphone11. The maximum number of concurrent sessions is two. When we try to connect another one devices, session(_:didInvalidateWith:) on the NISessionDelegate is called with NIError.Code.activeSessionsLimitExceeded. I'd like to know three or more concurrent sessions are running using newer version like iphone12. Does anyone have any knowledge?
