NV300 2018 Drivers armrest removal ?

[Dox]

Firstly thanks to admin et all for the inclusion of your forum ...... Had a Navara some years back ... dreaded chassis issue and managed a buy back from Nissan Nordics as I live in Sweden. .. Just bought a 2018 NV300 and am trying to remove the drivers arm rest to fit an aftermarket seat cover... centre cap removed and a plastic long squared centre piece revealed.... any clue on how to remove please?... Have put grips on it and tried to ease it free and even put a shifter on it to hopefully slacken it off .... but to to avail ....any one had any experience with this that they could pass on valuable info?

Thank you in advance
