Ulysses on macOS - share local content between user accounts [without iCloud]

Does anybody know how to share local Ulysses content across Mac user accounts?

I can see the local content is not stored at a user-specific directory: ~/Library/Containers/com.soulmen.ulysses3

I have a Admin account and a Standard account. I want to share all of my files between these accounts. But when I open my Ulysses on my new Admin account, I cannot see or specify the location of local files.

Solution 1:

You can add external folders in the sidebar:

For your use case it's probably easiest to create a shared folder in /Users/Shared and use Unix permissions/ACL to give read/write access to all users in question.
