As for setting up the plugin,
-First step is having the curseforge app. You can get that here CURSEFORGE
- Second Step open app and at the top of the addon you will see My Addons and get more addons, click on Get More Addons
-Third step use the search bar and type GSE or izzi and it will find a list of addons/plugins - Fourth step hit install
- Fifth step open up your game and type /gse
-Sixth step click options at the bottom of the gse window
-Seventh step click plugin - Eight step select the plugin you want and click it. That loads the macros
-Ninth step select the macro you want, create icon and move it to the bar
That’s it!!
More then likely went to detailed, but was not sure at what step you needed help.
I hope that helped you
