how do i do schematics

I'm confused I'm doing a modded Minecraft aternos server with world Edit mod, but I don't know how to do schematics I've used the plugin before, but it didn't work the same so I'm wondering how I can use schematics with the mod

I'm still not understanding i checked the mod documents and i can't find it please send a link or explain how. when i looked i saw what commands are used to do world edit in the world but i dont know how to actually put the schematics into the world so i can use //schem list and get a schematic
