Automator: Not able to import Screenshots from iCloud Desktop into Photos

When I take a screenshot, I want Automator, to use a "Folder Action" to find this Screenshot xxxx.png on my iCloud Desktop and import this file into the Photos.app.

The workflow works fine but the "Get Folder Contents" it doesn't seem to be able to identify any files/screenshots on the desktop :-(

The action “Import Files into Photos” encountered an error: “Import Files into Photos script failed.” and Import Files into Photos script failed.

Can anyone confirm? Or even better: Does anyone have a workaround?

Thanks and regards,
