Simple Minecraft-server

Hey linux community I got a question? Does anyone here know a little bit about hosting a simple minecraft server on Debian 10.6 on your PC?. My son likes minecraft and likes to play on my computer once in awhile and he asked me if I knew how to make his own server so I'm in the middle of that right now but need some help with safety precautions I went ahead and made a user " su minecraft " with no password so people can't ssh connect does anyone know how to edit the sudoers file permissions for the minecraft user? to where I don't need to use sudo? thank you for taking your time and reading not in a hurry to get this done so take your time if your helping or working with someone else.
