Sony alpha camera control through Python script

Hi All!

I am using RPI 4B as my companion computer and so far very successful in using modules present with python to automate drone.
I am facing issue with getting CAMERA info and CONTROL using pymavlink, mavsdk python with any script.
I am able to take photo through mavproxy command line using ‘cammsg’ command.

Can anyone suggest any changes in the setup as I’m using seagull cable to interface the camera with FCU.
or any script to do the same?
