This command will allow you to see how many servers the bot is in with the status, just customise the time on when you want the bot status to update.
const lib = require('lib')({token: process.env.STDLIB_SECRET_TOKEN}); // make API request
let servers = await lib.discord.guilds['@0.1.0'].list({
limit: 100,
});
let result = await lib.discord.users['@0.1.1'].me.status.update({
activity_name: `Amazing bot - I am on ${servers.length === 100 ? servers.length + '+' : servers.length} guilds`, // required
activity_type: 'WATCHING',
status: 'ONLINE',
});
