Need Help with connection VTX TBS Unify Pro 5G8 HV to Telem1 port

Could anybody help with settings how to connect VTX TBS Unify Pro 5G8 HV to the Telem1 port for transmit the OSD from Ardupilot.
Right now i have connected the VTX to Cube Telem1 Port:
TBS VTX Audio → Telem1 TX
TBS VTx GND → Telem1 GND
i have set the Serial1_Protocol to SmartAudio = 4
I have set the OSD_TYPE = 1
But no any OSD transmitted through the VTX

Need some help with Parameter settings
