I have a little question. Is PermissionsEx still accessible through the plugins search? I have tried to search for it myself but nothing showed up. Only some random add-ons for the plug-in itself. "Permissions" or "PermissionsEx" on the search bar does not give me anything close to the actual plugins. I also tried it with GroupManager and GroupManager X but same things. LuckPerms isn't really what I want but it's the only choice Aternos has in group plugins.
EDIT: Yes I have Spigot/Bukkit software running.
