Ughh Labrum is a painful one. Primary issue being lack of blood supply to not only the labrum but your Rotator cuff tendons. Internal and External rotation is what they'll have you do. Eccentrics - the lowering part of an exercise promotes collagen growth better then the concentric or up part of the movement so focus there. Would also strengthen your lower/middle trap and rhomboids. Thoracic Spine (upper back/spine) Rotation also needs mobility (stretching) as well as your chest - if these areas are tight.
Labrum more then anything takes time - good luck!
Google exercises if you need to BTW
