Code for a slash command '/users-with-role' that sends a message to the channel with the number of users for every *used* role. Your Discord bot requires the 'Privileged Intents' permission to function.

const guild_id = context.params.event.guild_id

const roleMap = roles.reduce((map, r) => ({ ...map, [r.id]: r }), {});
// Get a map of all roles and their counts
// Note: Only works for up to 1000 members
