Help replacing interor door handle on Citron C3 please.

[Jaroon]

Hi, the plastic door opening handle has snapped on my partners C3 so I ordered a replacement part from ebay. I've found some instruction on youtube how to remove the door panel but nothing about changing the interior handle only videos on the exterior. I'm not the best with spanners but will see if I can work it out. If anyone can advise me at all I'd be grateful ie is it straight forward or does the job require any unusual tools? Thanks
