Just for fun I uploaded a guess of these building footprints based on ESRI imagery alone, they may not be as accurate as if I had used Mapbox, but I wanted to give you an example of what to do in these situations. You can find the changesets via the top right of the task menu in the tasking manager (under task data), or near the bottom of the project main page (changesets in OSMCha).
