WebDAV folder permissions?

Operating system

Linux

Joplin version

3.2.7

Sync target

WebDAV

What issue do you have?

Recently installed Joplin and configured WebDAV synchronization.
Later, through a regular browser, I went to the folder intended for synchronization and noticed that it was fully open for reading.

Accordingly, the question
What permissions should be set for the folder and all subfolders for proper Joplin synchronization?

I'll answer my own question.
I put 700 on the rights folder, everything works fine.
