Hard to find photo with ACTION_OPEN_DOCUMENT dialog

The ACTION_OPEN_DOCUMENT intent opens a system dialog to choose a file. On the Nexus 5X I had trouble using this dialog to find a photo I'd recently taken. It wasn't shown in the list of recent items (which I think is the screen that's shown the first time you use this dialog), and I had to navigate to Menu > Nexus 5X > DCIM > Camera to find it.

The Downloads app on the same phone has a nav drawer item for Images, but the ACTION_OPEN_DOCUMENT dialog (which uses the same styling) doesn't.
