So you don't want to pair the devices when the mouse first connects to a central, but rather initiate pairing on the central whenever you'd like? I think this is up to your central, as the nRFConnect for Android application, for instance, can choose to initiate pairing to a connected device that is compatible, while a Windows computer will always automatically pair to a device identifying as a HID Mouse.
