LLDP-MED on AP-Group on XV2-22H

Good morning.
I have successfully configured LLDP-MED on CN-Matrix on one site. When I connect a phone directly to the switch it automatically configures itself to the correct vlan.
I have some phones that need to be connected in series to an XV2-22H that has a PoE out port. So I have this link Switch->XV2->Phone.
These phones do not receive the LLDP-MED packet and do not switch to the desired vlan. I searched in the ap-group section and on the XV2 cli but I can’t understand where to insert the parameters.
Can someone help me?

This feature is not supported in XV2-22H.

Tankyou for your reply
