This is a screen shot from a sales video. I am not familiar with how these are constructed, but first thing obviously would be to remove the drawers and doors. I see a TV mount so there will be some structure behind that to support the TV bracket. Be careful until you figure out how that part is fastened at the top and bottom. You don’t want to damage the slide box.
I would assume the cabinet is pin nailed and glued. I assume you are not trying to save any of the pieces for re-install. I would start tapping on parts of the face frame to remove the face frame parts and the dividers in the center…working carefully NOT with reckless abandon. No idea how the pieces attach to the walls and ceilings and you don’t want to damage those. Proceed slowly and carefully with your pry-bar/nail puller and hammer. You might find some wood screws attaching the side and bottom pieces to the slide.

I am just thinking out loud and speculating here. I really don’t know the real way to remove the cabinet. I answered this post as I was walking about the grounds of the asylum before supper. They are calling me to come take my medication now. Bye.
