I should check the code first, but my guess is that this is built using webrtc which was primarily created for realtime communication (including audio and video).

So my guess is that such feature can be easily added.

By the way, if you're using chrome, you can take share text directly via the clipboard. So that you can share from your phone, and immediately paste it in your computer, or vice versa.

By using kdeconnect (it has an Android app and a gnome extension), you have this done automatically. This means that you can copy a text in your phone, and paste it in your computer, as well as the other way around.
