In Debian 9, there's a FUSE-based filesystem `jmtpfs`, packaged with the same name. It seems to work quite well with Android 8 at least. Perhaps it is available as a package for Mint too?

As it's a real FUSE filesystem, it is actually mountable, and so usable from the command line.

The source code and the developer's introduction to `jmtpfs` is [here][1].
