Idea from ResurrectionChest by MagmaGuy which has not been updated to 1.21.11 yet. ResurrectionChest source code was not used as a reference or inspiration for this plugin's code.

I cannot guarantee this plugin is perfectly made as there are most certainly ways I could've done it better. DM me on discord (akaLuke) or make a github issue if you find problems.

I will only consider updating this plugin if ResurrectionChest is not updated for newer versions, this plugin stops functioning in newer versions, and there is a demand for an update.
