KDE Connect is an open-source application which provides integration for your phone and your desktop, such as allowing you to use your phone as a wireless trackpad and presentation remote, or for replying to incoming text messages from your computer. Come and be a part of building a transparent and secure bridge to simplify your world!

KDE Connect has a Plasmoid that acts as a UI for most of KDE Connect's features.

For this task, we want to make it possible to share files from the Plasmoid.

Add a button that opens a file picker (https://doc.qt.io/qt-5.11/qml-qt-labs-platform-filedialog.html) and send that file to the connected device.
