If the "Publish" option doesn't appear here, it may be due to users not having a Google account linked to their VR.World account for this purpose - see this article for more information on how to do this.
Upon selecting to "Publish" a capture, a confirmation prompt will appear where users must confirm the publish action by clicking "Publish":
