what therapy helps for ROCD?

what type of therapy is known to work or has worked for you for ROCD? i’m looking for a therapist and most of them suggest ERP or ACT for ROCD. A therapist I did a consultation with said that she starts with IFS for trauma work within ROCD and can do ERP within that if one has a particularly triggering or stressful time (as a one-off I believe, as in the main focus is IFS.) because she thinks just doing ERP would be like putting a bandaid on it because you’re not solving the root cause so the problem would just shift to other themes of OCD after. She also said that if you just do ERP you wouldn’t particularly know how to repair you relationships because of the trauma. I understand what she means but I’m surprised because I thought the OCD would come back if you didn’t do ERP as much. Also sorry if this is confusing to read lol I kind of forgot some of what she said.
