I do not see the Xiegu on the list of supported radios.
I just downloaded the manual and radio control details are quite lacking.
If it were me, I would try to select various radios to see what *may* work.
I certainly do not speak for the N1MM+ team (just a very pleased longtime user) but it's my opinion that
I doubt they will develop a radio command set for a radio that's so far off the beaten path and rarely ever talked about.
(searching Xiegu on here & cqcontest brings up a total # of hits I can count on one hand.
Until it it, you are likely on your own.
