Preview field visibility of different user profiles
Hello everyone!
We're excited to introduce an option to preview how fields are visible to different user profiles when they have permission based access.
Administrators can set field permission for different user profiles based on the business requirement and the sensitivity of the data. It allows them to protect confidential data from unauthorized access.
Fields can be set as Read Only, Read & Write or Don't Show for different profiles.
Using "Preview" admins can view how these fields will appear in the layout for different profiles. For example, the Phone number field can be read only for users who have agents profile and read/write for support administrators.

The preview option is displayed when the layout is edited.
For more details kindly refer to the help doc.
