If you have an existing space in Webex, you can convert it into a universal channel and start inviting external contacts to chat with you.
Note: This feature is only available for spaces that aren't added to any teams. If your existing space is in a team, you need to first remove it by clicking the gear icon next to your space's name.
Convert an existing Webex space to a universal channel
In a direct chat with the Mio bot, type and send "create" to pull up the create channel menu.
Choose Existing space.
Find and select the Webex space that you want to convert into a universal channel.
If you can't find your space from the drop-down list, please make sure that the space is removed from the team it's in.
Congratulations! You've converted your Webex space into a universal channel. Copy and share the invite link with any external contact. They will need to install the app and authenticate as well.
