Bot must have Manage Roles, View Channels, Read Message History, Send Messages to do anything, all other roles are in case I expand the bot. Key features:

• 1. Verifies Lichess / Chess.com account ownership by inserting a key into your account settings.
• 2. Gives you a role by your highest current rating in all time controls except Bullet.
• 3. Gives you a role by your current rating in Puzzles.
• 4. Gives you a role by any title you have in either your Chess.com / Lichess account.
• 5. All rating roles can have whatever gap you want*.
• 6. Verifying accounts synchronizes between all bot's servers.
• 7. Supports buttons to retry a link if you get hit by a rate limit or by the verification procedure.
