What are direct shares in Android One? Whenever I use a standard system Share dialog in any of my apps (Motorola One with Android One on-board), I see a huge empty panel in the middle of it:

The second line never changes and always shows &quot;Direct share is not available&quot;. For as long as I've beem using this device (Motorola One; years) I have never seen anything else there.
What is direct share? Why it is always disabled / not available in my device? How can I enable it or even better -- get rid of it and hopefully hide that part of standard Share screen, which occupies the most space of it and is pretty much completely useless.
With direct share you can share plain text trough an app which can use this feature. Also, with direct share some apps display some contacts.
