Ikea Besta Tombo wall cabinet - glass door / disassembly

hello!

I have a request: we have a wall cabinet with the Besta tombo display doors. But since we didn't assemble it ourselves, I unfortunately have no idea how to take the doors apart/disassemble them in order to frame something inside. And somehow it's not obvious - for example, what exactly do I do with these gray clips that are between the frame and the glass?

I would be very happy for help - many thanks in advance!

I also have the doors... but I can't really help you, since my husband always likes to do everything alone and he doesn't even remember how he did it :rolleyes:. Anyway, he took off the grey things, but it also took him ages to figure it out here :D

If I were you, I would go to Ikea and have them show me on site, since they have the doors set up there too...
