How do I bring up "trackers on this page"?

That's interesting!
But your screenshot shows a window on the right with "trackers on this page". Mine doesn't - so I can't click on it. How do I bring up that window?

Meanwhile I clicked on the eye at the bottom anyway. A "Privacy Report" window opened, which showed a couple of blocked "websites with content on the current page". Neither of them have the word Brightcove. Both have "twitter".
Then I selected from this same "privacy report" window to show all websites. There were many "websites with content on the current page but the only blocked ones were again the same 2 with "twitter".

Perhaps I should unblock those? But now I have to go to work. happy I'll wait to hear back from you. Thank you.
