Have an urgent need to touch-up a photo for a memorial.  Using MacBook Pro with Monterey.  Photo is a black-and-white image that has some white spots where it is suppose to be black/gray.  Somewhere somehow in the past I believed I experimented with a tool within Photos where I could use some kind of brush/marker to outline the spot to be adjusted then somehow change that spot to color of the surrounding area.  I did that once on my old MacBook Air years ago, and now (age related, I'm sure) I have zero idea how I did it then or how to do it now.  Have checked YouTube videos but no luck.  Anyone please?!?
