Which permission type is NOT relevant for using Layouts?

The option that indicates a permission type which is not relevant for using Layouts is related to the concept of "Lock" in the context of Object Security for Layouts.

When configuring layouts in a system, particularly in environments like Relativity, the primary permissions that govern access and modifications to layouts include the ability to view, edit, and set visibility options for specific tabs and objects. "Lock" typically refers to a state or restriction that prevents changes to a layout, but it doesn't play a role in the basic permissions needed to utilize a layout effectively.

In the context of layouts, permissions concerning visibility and editing are essential, allowing users to experience appropriate access to the data presented and the ability to modify layouts as needed. The "Lock" permission does not facilitate interaction with the layout itself, such as viewing or editing, but instead would be more about restricting alterations to a completed layout configuration. This makes it an irrelevant permission type when considering the active use of layouts.
