Right Bumper (On the left when board is flipped)
Jump from the top left pin to either side of R24.

Left Bumper (On the right when board is flipped)
Jump from the top left pin to either side of R23.
Another option is to clear solder in the top left hole, and slide a jump wire through the hole (if the wire is thin enough), then route and jump to either side of R23.

Jump Wire
What you’ll want to do is jump (solder) a wire from the pin of the tactile switch to the point mentioned above, depending on which switch is causing the no response issue if the pad is damaged. While you could purchase a jump wire as seen in the list here, you might also be able to scrounge up some from around the house. Some common jump wire used for purposes like these is a strand of speaker wire or wire from an ethernet cable. Both work equally as good. If the wire is bare, just be sure to not make contact with any other metal and/or points on the board. For example, if it touches ground, the switch will now show the opposite: constantly pressed.
