how to disassemble the front center armrest (access 12V outlet)

[Ande]

In my 2016 model S - I plan to make a hole for USB-C (PD) outlet in one of the places marked in blue:



How do I disassemble that unit in order to access the 12v, and mount the USB_PD electronics behind?
(the electrical stuff is absolutely not an issue, I just wonder how to get to the inside of it.)

Any video or description that shows this process would be much appreciated.
