Longterm use plateauing

I have been on Mounjaro for 19 months. Almost a year at 15mg. I have lost about 112 pounds from 334 to 221. I go to the gym and lift heavy weights 3-4 times a week with some functional cardio. I have not lost any weight in 5 months. However I have still lost some belly/waist circumference.

I am still 30 pounds away from my goal. I would like to weigh between 190-200 pounds.

Any advice on getting over this 5 month no weight-loss hump? Any advice on diet, exercise, lifestyle etc. is much appreciated!
