According to the manufacturer link: ... Scan your documents directly to the cloud via Brother's mobile app and share your documents with colleagues from anywhere ...
Sounds to me like "scan via mobile and then first to the Brother Cloud and then to yours" with appropriate write permissions for the BrotherApp on your cloud storage.

In the Brother software on Windows at least you can scan directly to G-Drive, Onedrive. I think there are more possibilities.
I don't know if the scanner can scan directly to the cloud without being connected to a PC.
