How to use sense-edge-mask?

I am registering interrupts for many pins:

This only works for the first 8 pins, because from what I understand the GPIOTE peripheral is used and that has only 8 channels.

As a solution I found that I should use sense-edge-mask in my device tree:

However, with this setting, the interrupts don't work at all.

Do I need to change my code as well in addition to the device tree setting?
