Plugins Permissions for noobs

Hi, its the first time i put a question in a forum:

Im trying to get autosmelt in my server, i also want to get skins, but i dont know how to make permissions of the plugin page work; i see a lot of tutorials and threads but that dont help me at all. I need first of all someone tell me where to put those things (in text while playing, to the console or on a file) i dont know and it soo frustrating; also permissionEX is not here to use, so a lot of threads can not help me.

Sorry if is alredy a thred like this, im too new on this, and thak you! also if its a mod to do this quick and forget about plugins can be the best way to solve this problem to me. thank u again.

i play 1.12.2 with magma for plugins and mods

thanks, now i got something for the permissions:

after install the plugin i got the global permissions typing in the game: (my username is piny)

/lp user piny permission set autosmelt.reload

from this plugin https://www.spigotmc.org/resources/auto-smelt.71576/

Now i get the permission, but i can not make work the commands yet, if i do:

/asreload

the game tell me there is not a command for that.

Im getting close to make it work, if anyone can tell me what i m missing i ll post everything, so the people with same problem can fix it from this thread.

And thanks again!

that was a test, i alredy did it for this one too https://www.spigotmc.org/resources/autosmelt.16778/

now i see the last one was for 1.14-1.15, anyway im trying for all 3 types (i remember to delete it afeter test)and commands still dont work

https://github.com/lucko/LuckPerms/wiki/Usage this is a good post to get started but still dont solve my problem; at this point can be a compatibility problem? also clothes from ice and fire dont look as they should; thats for another moment but can be relationed.

also i did give permission to luck perms:

/lp user piny permission set luckperms.* true

Thanks.
