Issue when control gimbal SIYI ZR10 using mavsdk

MAVSDK
1

I cannot control the SIYI ZR10 gimbal when using mavsdk and QGC.
I connected the gimbal to pixhawk 6x using uart via telem 3.
I set the parameters MNT_MODE_OUT = MAVLink protocol v2 and MNT_MODE_IN = MAVLink protocol v2.
Help me please.

Does the SIYI ZR10 support the MAVLink gimbal v2 protocol? And do you have the latest gimbal firmware flashed?
