Qt 6++ Bluetooth Pairing

Question

Info: bluetooth-changes-qt6

The pairing agent related API was removed without replacement. This includes pairingConfirmation(bool), pairingDisplayPinCode(..) & pairingDisplayConfirmation(..).

I would like to know:

1. Why it has disappeared
2. Even though it says there is no replacement. If there is any alternative way.

Thanks :)
