Terminal Joplin Dropbox Symbolic Path?

I’m using Android Joplin. I’m synchronizing to the drop box.
And I installed a drop box app and terminal Joplin on my Ubuntu 18.04 laptop. a safe and soundly
Which path should I ‘ln -s’ the Joplin sync folder in the dropbox? I’d like to use Joplin, a terminal on Linux.

once you installed joplin, trigger the sync process and joplin will ask you a token to grab on dropbox to allow joplin to sync on dropbox.
once it’s done, joplin will sync its content from dropbox locally (and in the other way), no need to use a symbolic link.

I found it!

~ $ joplin sync

Its Very Good.
