Rename server with API
it's really easy. Firstly we need to get our server id. It's the last few letters in the url

Copy that, you will need it
Now add this to your .js file
main.js
client.renameServer("Your server ID", "Your New Server Name").then(console.log("Renamed"))
Now replace Your server ID with your server id and enter your new server name.
And then when you start the script it should log Renamed in your console
console
Renamed
