I've seen other pages have events lined up in a carousel immediately after their "About" section: https://www.linkedin.com/help/linkedin/answer/a552496/create-an-event-from-your-linkedin-page?lang=en
There is also a "Past events" section, but I'm not sure if we can add backdated events. It could be worth trying!
@malayajac, this might be useful for the 1st November call – we can link to the FOSS United event page (when done from the chapter dashboard) from LinkedIn.
