This snippet allows your members to add specific roles to themselves using a prefix command, `!join ROLENAME`. Kindly read the comments in the code to understand what you need to set up. Credits to the [GitHub Repository](https://github.com/AnIdiotsGuide/discordjs-bot-guide/blob/master/understanding/roles.md#get-role-by-name-or-id) for the find() method used here.
// ensure that the bot's role is above the roles on the position in server settings
const lib = require('lib')({token: process.env.STDLIB_SECRET_TOKEN});
const event = context.params.event;
const command = `!join`;
/*
**Purpose**
- the variable on line 17 is the source of which roles you want to allow the bot to add from
- only specific roles are allowed so that members cannot add a role that has a certain requirement (example, Nitro Booster)
**Setting up**
- write the name of the roles you want to add, following the respective format (example, `A1` || `A2` || `B1` || `B2`)
- visit this site to learn more about OR operators: https://www.techopedia.com/definition/3486/or-operator
