Tailgate cannot be opened.

Hello, my Murena ist showing his femine side and being bitchy. The Bowden cable for the tailgate has insufficient tension on the right-hand lock. As a result, I am unable to open the tailgate.
How can I raise the tension slightly from the outside to access the adjustment? Remove the belt, remove the B-pillar trim, or is there a better approach?

Might be able to open it if someone presses down on the glass a bit as you pull the lever on the b pillar.

We tried that. It works on the left, but unfortunately not on the right. I'll probably have to remove the lever in the B-pillar. Hopefully, it's only held in place by the one visible screw in the base plate.
