"A-pillar" trim - W140 Mercedes

[86560SEL]

The lower part of my a-pillar interior trim in my W140 is pushed out at the bottom. I was assuming it was a broken clip or something. I can push it back in, but over time it will slowly work its way back out. I got some new clips, but now I cannot figure out how to remove the trim completely to put on the new clips I have. Do I have to remove any other trim first to get this one out?

Thanks!
