Is there any way to know the major and minor beacons detected in the iBeacon background?

I can't use RangingBeaconsInRegion for background processing, so I use MonitoringForRegion for detection, but MonitoringForRegion only knows the UUID, and I don't know the major and minor.

I'm also looking for a way to know major and minor in the background.

Could you tell me if there is a way to take major and minor in MonitoringForRegion, or if there is an alternative?

Thank you for your cooperation.
