Hybrid Zoom/live event: sharing media

[SallyW1]

I attend a course which has both real-time, in person attendees AND people attending remotely, by Zoom. The tutor can use the Share button to show illustrations to people attending in person, using the overhead screen in the lecture room, but those attending remotely,  by Zoom, cannot view those illustrations. At other times, Zoom attendees can view the media, but not those attending in person because the images don't show on the overhead screen. Can someone advise please?
