How to properly connect T2D-10X with Pixhawk black cube?

Hello! I’ve been trying for a couple of days to controll the gimbal of the camera and failed. I can’t select camera type and MNT_… Parameters are missing except for MNT_TYPE1 and MNT_TYPE2.
I recieve image from the camera on my RC, but I can’t configure the PTZ.
I tried looking at different tutorials but no one seem to have faced this. Maybe it’s something simple I just can’t see.
Any suggestions?
