Unable to copy a single file from a 1fichier password protected shared folder

yes. It shows all the files in the folder:

rclone ls remote1: -vv|more
<7>DEBUG : rclone: Version "v1.57.0" starting with parameters ["rclone" "ls" "remote1:" "-vv"]
<7>DEBUG : rclone: systemd logging support activated
<7>DEBUG : Creating backend with remote "remote1:"
<7>DEBUG : Using config file from "/home/me/.config/rclone/rclone.conf"
111385677 0035 - a.rar
14755124274 0036 - b.rar
2643884961 0037 - c.rar

I don't own the shared folder, so I can't clean it up. Also, do spaces in the filenames matter?
