Cannot "apply clip" from a shared album to a drop zone

Hey guys -

Been working with FCPX for a while as a hobbiest, and upping my game by trying out plug ins. My challenge is that the videos I do typically include videos/photos from shared family albums.

I've watched several videos on adding media to the drop zone, and every time, it looks super easy. However, when I attempt to select a video from a shared album, the "Apply clip" button is not enabled.

In this screen shot, I'm in the photos section. I can't get "apply clip" to be enabled.

If I drag the selection into the storyline, it will add it to the media section of my event. I can then go back to the media section and select the same clip. At this point, the "apply clip" becomes enabled.

In this screen shot, I'm selecting a video from the "Media" section. "Apply clip" is enabled here on selection.

So the question here is "do I have to import all my photos from the shared album into the media library for the project in order to apply them into the drop zone?" If so, that seems like a total pain! Happily welcome suggestions on the most efficient way to handle use of shared album photo content in FCPX, even if that means an import of some kind. <-if so, how?

iOS: Mojave 10.16.6

FCPX: 10.4.10

^^^ I know... I'm working on upgrading. :)

Thanks in advance for anything I'm missing here.
