The best way for the administrator to satisfy this requirement is to edit the Lightning Record Page
and change the Template to Three Regions. A Lightning Record Page is a type of page that displays
details and related information about a specific record in Lightning Experience or Salesforce mobile
app. A Lightning Record Page can be customized using the Lightning App Builder, which is a tool that
allows administrators to drag and drop components onto a page layout. A Template is a predefined
layout that determines how components are arranged on a page. A Three Regions template is a type
of template that divides the page into three columns or regions. The administrator can edit the
Lightning Record Page for the Order Summary object, and change the Template to Three Regions in
the Lightning App Builder. Verified Reference:
