Adding New Message To MAVLink and Displaying it on Mission Planner

We need to add a new message to the MAVLink, and after adding it we will need to display it on the “Quick” tab of Mission Planner. If anyone here knows how the current messages are being processed in Mission Planner , We are not concerned about what Drone side will do to the message.

In fact my assignment is to find out the lifecycle of a message that is being received from the Drone “not sent” from the drone", and displayed on the Mission Planner. Our next step would be add a custom user message to the MAVLink and then display it.

I would appreciate any help.
