Plugin Golden Crates

I have a problem with one plugin - the Golden Crates plugin. I used to play my friend's servezre and this plugin worked for him and I can't find it in plugins, because then "No plugins found" pops up. My friend's server was on version 1.17.1 and mine is on 1.18.2, but when I switched to 1.17.1 I couldn't find it either. Is it some aternos bug or I have some old version of aternos XD or what because nvm and this plugin in my opinion was the best plugin for making cases in gui and I already mastered it well.

PS: I am Polish and I can not take English, so I copied from a translator.

It's called ExcellentCrates now.

Thank you very much! I never thought there was anything else to call it.
