Creating a button in the "Data" tab - tabControlactions

Hi! I am asking for help in solving my problem:
Create a button in the “Data” → “Action Management tab” section, which sends the “DO_PARACHUTE” command to the device.
Couldn’t figure out how to call this function and how to send this request (for language c#).
youtube or are the instructions good and clear for development? how do I add new requests and send them?Thanks!
