A permission allows you to define the rights that a group of users has over a space. For example, if you have a New Invoices space, you can define that the Accounting group has write permissions on the Invoices space.
To add a permission, go to the Permissions tab in the Users menu. Click the “New Permission” button.
Next, you will have to define which space a group will have rights over and what type of permissions.
A minimum read permission is required for a user to be able to view the documents in a space.
