How to remove this bolt from the bedframe

bedroombolts

This is my first time posting in this forum but I wanted to get some help from y'all regarding removing a bolt from my bed frame. I bought a used bed frame and I need to dismantle it to shift it into my room. Here is an image of the bolt.

Could you please tell me what tools I would need to remove this screw (the silver nut on the left) as well as how I should go about doing it. Thank you, I really appreciate the help from this community 🙂enter image description here

Looks like an IKEA bed to me - something like the MALM or the HEREFOSS.

You first remove the metal rail, then undo the nut. The manual depicts a wrench (ikea part 113453) but a regular metric 13mm wrench reportedly works fine. From the assembly instructions:
