if(msg.content.startsWith(prefix + "addbalance") && msg.member.permissions.has("ADMINISTRATOR"))I need help changing command access from ADMINISTRATOR permission to only my discord id. I want to limitate the command only if I use it because I have many ADMINISTRATORS in my server.
You can change the second condition in the if statement to check if the ID of the user is yours.
if (msg.content.startsWith(prefix + "addbalance") && msg.member.id == YOUR_ID))
