I solved this small incompatibility that prevented you from using the plugin on servers higher than 1.12.2.

I have updated the plugin, but now I will no longer update it, you can use it on your server and you can make forks or edits.

I have corrected some errors of the plugin since what I have to do is update the plugin while I am advancing with the plugin
1 ➜ Added compatibility checking of an available plugin update
2 ➜ I added the command to see all the available permissions.
Command: / autogg permissions This command is only used with the permission: autogg.admin or having operator.
