Hello there,
The support said what to do to have a new plugin in Aternos, so here i am.
The plugin name in : EssentialsChat, he is really important for an another plugin (GroupManager). Whitout this plugin GroupManager can’t have full utility so please if you can add EssentialsChat in Aternos I’ll be very happy! 
I found this link for EssentialsChat : https://www.spigotmc.org/threads/essentials-chat.284144/
The first answer gave a link, a download link (the first link, cause there is one for EssentialsX and an another for EssentialsChat). (If you don’t find the link: https://hub.spigotmc.org/jenki…ialsChat-2.x-SNAPSHOT.jar ).
A secret fan
PS : Sorry if i did some spelling errors ! I can’t Do better !
