Removing unused snaps

How can we delete the following two snaps from the Snap store? We have two extra snaps that we would like to remove: “8bitcommando” and “skullbasher”

Setting the two snaps to “private” would be fine too, although I am unable to set the latter snap to “private”

This request has not been added to the review queue. It should be placed in the appropriate store-requests subcategory using the subcategory template for classic-confinement, privileged-interfaces and aliases requests.

Just close all existing channels…

Thank you for the suggestion. I am not sure if I am missing anything, but clicking on the “close” button under “latest/stable” does nothing in my case.

What is the “official” way of removing snaps from the store?
