Remove Ikea furniture cover 115754

Dear Ikea friends,

I have successfully assembled and mounted a Hemnes mirror cabinet (the one with a mirror). Now I want to lay a light cable and for that briefly remove the white cover in the corner with No. 115754 to route the cable along there. The cover just won’t come off! I mean, I only clipped it on during assembly. If I apply more force, it will probably break. Does anyone maybe have a Hemnes mirror cabinet or another product that they have disassembled before and can give me a tip on how to remove the cover?
Best regards

Hello, feel free to use more force. The cap will withstand it. If not, get a new one from customer service with the part number.

Thank you, then I will be more aggressive! :)
