How to correctly compose an lftp script so that the latest file is downloaded by modification date?

Question

FTP

In general, I started writing the script
#!/bin/sh
lftp -u login,pass 10.10.10.10 << EOF
cd /incoming/files
ls -tr | tail -1
EOF
Shows the most recent file by modification date. If you add a mirror, then it downloads the entire directory.
Tell me how to finish it!
