End users may need to send cross-platform messages in private Slack channels. To sync private channels, admins will need to add the Mio app to the private channel before continuing with Channel Sync instructions.
Syncing your private Slack channel
Navigate to your desired private channel.
Click on the name of the channel.
Under Apps, click Add an App.
Search for the Mio app. Click Add.
You will now need to re-import your Slack channels and sync them with a secondary platform. Follow Step 2 onwards of our Channel Sync guide to do so.
