3rd door Pillar molding replacement?
 

I have the part, but I'm not sure how to safely remove the old molding. It's a 2011 Cooper S Clubman, and the molding in question is here: https://www.minipartsdirect.com/oem-...ng-51137167236

It should be a very easy fix, I just want to make sure I don't make any stupid mistakes that result in having to then replace the whole window, since the molding is affixed to the window glass with double-sided adhesive tape. Any tips?
