First oil change help

Trying to do first oil change on my 2016 570 xmr. I have removed the side panel and am trying to remove the footwell. I have removed all pushpins and nuts and bolts. It is loose now but I can’t seem to get the footwell separated from the front and rear fenders. What is the trick to this? Is it possible to change oil filter without removing this. I really like this atv but nothing is easy to work on. Thanks
