Rear Tailgate Manual Lock Help
 

Hi All. My 2019 XC60 has a fob/locking issue - car isn't recognizing the fobs - I've got a diagnostic fix appointment booked for 2 weeks from now.
I've figured out how to manually lock all the doors (using the lock insert on the side panel of all passenger doors), BUT.... and here is my issue:

I can't figure out how to manually lock the tailgate. I'm leaving the car at the airport this weekend before the dealership can fix the main issue, and I can't lock the tailgate.

Is there a way to manually lock the tailgate, or is this a Volvo oversight issue?

Thanks in advance for your suggestions for fixes.
