To duplicate an entity, creating an entity with the same class as well as defined attributes, focus your attention on the toolbar. Find the dropdown labeled More and click on it to expand it.

With the More dropdown open, select the option labeled Duplicate and the web page will automatically navigate you to a copy of the entity, allowing you to make any changes without modifying the existing entity.

The new entity's name will be prefixed with Copy of to indicate that it is a copy of the specified entity.
