I migrated from Cisco Jabber to Webex where I could collaborate in a group with audio and screen-share.

As a paying customer of Advanced Messaging we cannot Share or Call to a group/space. This feature is available with 1 person in a Chat.

Sharing and conferencing with more then 1 person should be standard feature and not requiring a Meeting License or have a 40 minute limit for internal collaboration within the same organization who are paying Flex customers.
