I created an at-home spigot server so that I can use voxelsniper to build stuff. The server is running fine, but I can't use commands because I'm not an OP. I've tried editing the ops.json file, but it doesn't seem to work. I don't know how to open the console, and typing the command in chat doesn't work. I'm on version 1.15.1, with no plugins installed yet. I apologize in advance for not knowing what I'm doing, I'm very new to this sorta thing and I have zero experience in the java language.
