"share" files from android to the stick

Many android apps have a share-function to give away files to other apps. The gallery for example can send pictures directly to Whatsapp or other apps and they use the received files.

In the menu for choosing an app to share the file with I can select the Connect app aswell, so this app is registered for receiving files. However when i choose this option, the Connect app starts as usual and doesnt use the shared file.

Is this intended or a bug? My Intention is to send a file directly from another app without having to open my file explorer inside the connect app and selecting “upload”.

Thank you in advance,
