hi - so i have a late 2019 macbook pro and i recently found the keycap for the left arrow key came off. while trying to get it back on i ripped off the actual switch that holds it in place. i have lost all pieces except the switch, so i don't have the rubber dome or the keycap. is there any place i could get this replaced/fixed ? just cried in school about this so I'm looking to get it fixed as soon as possible so i don't make a fool out of myself.
