Sorry for the confusion about openfire meetings. See this blog for more details - Openfire Meetings as an alternative to Zoom
I am using latest version 0.9.13. You can find it here - https://github.com/igniterealtime/openfire-pade-plugin/releases. The Pade version requires both ofmeet.jar and offocus.jar plugins.
You only need pade chrome extension or the pade openfire plugin if you want to add Converse chat/groupchat and have unified communications.
