Mavlink commands to set flight modes that are not listed

Thanks Alvin, thats alreay helpful.

Additional this is relevant:
https://mavlink.io/en/messages/common.html#MAV_CMD_DO_SET_MODE

So I set Mavlink command “172”, Param1 “22” (for the Flowhold Flightmode in my case).

But nothing happens. I guess I need to send additional Param2 which contains “Custom Mode”. Does anybody have a reference how to set this parameter?

For reference here are the Plane/Quadplane modes listed:
