Gsx pro elucidations

So i bought this program and i dont understand some things…i also red the manual but it did not give me much help.
So basically i use msfs with Gsx pro+FSLTL+LatinVfr global+LatinVfr jetway pro…is there any incompatibility with these programs together?
If the answer is no i wanna now why in the airport why the AI aircraft dont use gsx pro for tugs or jetway…and also i didnt see livery from gsx pro,but i think only from the default and latin vr global vehicles…hope i could make me understand what iam saying…what does gsx pro do to AI aircraft and airports?if i dont call it for my personal aircraft i mean…thanks
