Hello, help me Im dumb. Addon to control relays

Im trying not to be a forum noob, but I seem to keep running into the same issues. Honestly all that I want should be really simple. However, I dont know anything about coding (go figure). I have Kodi set up on my pi 3. I have successfully SSHed into it. I cannot however activate any terminal commands such as sudo anything. All I need is an addon that i can click on Kodi’s main screen that can turn on/off a relay 3.3v+ on, 0.0v off (using GPIO). I actually need 4 different ones that I can turn on and off as needed.

TL;DR Want an addon (or 4) that can turn on/off GPIO with a mouse click.
