How to change the Bot Link
Your bot's "m.me" link is defined by your Facebook Page's username.

Each time you change the username of your Facebook Page, you need to Refresh Permissions in ManyChat for the changes to take effect.
You can refresh permissions by clicking the button in 'Settings' → 'General' in your ManyChat account to apply changes.
That's it - you're awesome!
