Guided_enable command

Hello,

I’m flying arduplane 3.9.8
I would like to use the GUIDED_ENABLE command in flight plan
GUIDED_ENABLE is available in arducopter flight plan but not in arduplane

I’m trying to find a way to set the Guided flight mode into a mission for a vtol plane
We use this mode for precision landing in Africa where we deliver health products by drones for NGOs.

So you know an other way to set this Guided mode into a mission ?
I’ve already tried to use the DO_SET_MODE command
I’ve tested it simulation it does not work and I don’t the the value to use in “mode#”

thank you !
