Thanks to @sid he showed me a way to log into my docker machine via SFTP
On a mac, download the free Cyberduck from https://cyberduck.io/
Create a new bookmark
Server: 111.111.222.100 (Change to the IP Address of the Docker machine)
Username: root
Password: BLANK we will use an SSH Key File
SSH Private Key: ~/.docker/machine/machines/Target Name from Wappler/id_rsa
Try Connect, it should come up with a security alert about an Unknown Fingerprint, which you accept, and then connect to the /root folder.
Go up a directory to /
Then navigate to /var/lib/docker/volumes/ProjectNameFromWappler__TargetNameFromWappler_user_uploads/_data/
And now you will be able to manipulate your user uploaded files directly through FTP
