It's important to consider the specific context when choosing a synonym.
For example, if you're talking about a public figure who was previously canceled and is now regaining their popularity, "rebound" or "make a comeback" might be appropriate. If you're talking about a person who was ostracized and is now being welcomed back into a community, "reintegrate" or "rehabilitate" might be better choices.
