Expected Behavior

Cancelling a file upload should simply dismiss the file picker or cancel the pending upload, while keeping the Nextcloud Assistant window open and usable.

To Reproduce

• Open Nextcloud Assistant app.

• In the chat window, click the button to upload a file and open the file picker.

• Cancel the upload.

• Observe that the Nextcloud Assistant window closes on its own.
