WebEx allows for collaborative spaces through Webex Teams. A Webex Team space can be created for the entire class or specific groups of students. In each team space, members of the team can post comments, share files or images, and have online meetings. Team spaces are great for group projects or sharing information with your class that is outside of required readings (e.g., links to current events, informal communication, et cetera).
Use the waffle icon to see available options - including sharing files or making a call to the team space. Here, you can also see who is active in the Webex space with you.
