Is There Any Plugin for ShulkerBox

I would like to know if there is any plugin or feature that can convert a Shulker Box into a backpack, so that, when right-clicking, the player opens the inventory contained in the Shulker Box.

i usually just get stuff like sophisticated backpacks or travelers backpack rather than using shulkers

Note how they dont provide links to the plugins (its a spigot plugin), but instead a link to spam.

Do not click the link

My guess is this is a AI generated reply and then a link just put into the bottom. We have been getting a lot recently so wouldn’t suprise me if its scheduled to just create a random account, find a random thread and then make an AI reply and just put a link to spam at the bottom
