So an avatar is like an attendee. So, it's someone that has a physical body virtually that can interact with other attendees, can visit booths and interact with sales representatives, can speak, can do a video can chat, can schedule sessions where the keynote speaker privately. And the viewer is just a ghost user that can access a virtual environment and not have any interaction with all the participants. So an avatar is like, imagine a real human. A viewer is just a ghost person that is around there that no one can see and can access the rooms that the event organizer allows and doesn't have any sort of interaction. Thank you so much.
