Retrieving the invite link
Find the Mio app and send "/mio menu".
Select My Conversations.
Find your existing universal channel from the drop-down list.
The Mio app will show your channel details.
Copy and share this link with any external contact. You can also send a direct email invite to your contact's inbox without leaving Slack.
Your external contacts will be asked to install the app on their own chat platform, whether it's Slack, Microsoft Teams, or Webex.
Inviting contacts directly from a universal channel
Type "/mio invite" directly in any universal channel (not with the app).
Note: This slash command will only work in existing universal channels in Slack.
