How do you replace 2019 left rear reflector?

Hello! I'm new to this forum. I just purchased a used 2019 Mazda cx5 grand touring yesterday and when I got home, somehow part of the left rear reflector got unhooked /unattached from the rest of the car! Anyone know how to fix this? I hope I don't have to disassemble the bumper....

Fairly sure there is a door in the wheel arch liner to reach through. The European models need access to those reflectors to change a bulb.
