Screen Actions provide a way to capture the logged-in user when submitting an “update one item” form or “add one item” form.
However, this is limited because it only captures user’s email (for normal properties) or user’s page id (for relations). To make this more useful, we will introduce another option called User Properties. So you can capture the logged-in user’s properties in Screen Actions.
For example, when submitting the form set the “Project.Client” to “User.Client”.
