Inherited this in 2020, how to restore?

I’m helping a client restore an old site, they shared a dropbox folder with me containing a backup from this plugin. I found a link to the plugin itself in another thread in this support forum, I am able to install it and connect to dropbox inside the plugin (“Dropbox successfully connected: UID xxxxxx”) but I don’t see a way to restore.

The readme.txt inside the plugin zip says “If you are connected, you will see the list of all backups in your plugin. Click Restore button to recover the one you need.” I don’t see any list of backups.

If I go to the dropbox Apps folder there is a WPAdm subdir, and inside that a www_xyzclientsite_com and inside that several backup subdirectories like www_xyzclientsite_18_43 (and other numbers).

Any idea what I need to do to get my plugin (which is on an local MAMP install of WordPress 5.4.1 with no domain name) to see and restore the files on dropbox
