Most surgeons and dietitians agree that "pouch resets" are just crash diets. They don't actually reset your pouch (and nothing will, its an organ, its doing what its supposed to and doesn't need to be "reset") or do anything for long term weight loss. What WILL help, is tracking what you eat and staying in a calorie deficit, hitting your protein goal, ensuring you are getting in plenty of water and staying hydrated, and moving your body regularly. Go back to the habits that helped you lose the weight to begin with.
Additionally, some amount of regain is completely normal. Most WLS patients find that their lowest weight isn't their healthiest weight long term. If possible, maybe check in with your surgeon's office and get their insight as well.
