The purpose of a Site Map is to define the navigation for a Power Platform app such as BrightWork 365. Site Maps are created using a tile-based Site Map Designer. To modify the BrightWork 365 Site Map:
- In Power Apps, load and edit the BrightWork 365 site map located in your unmanaged custom solution.
- Choose a Site Map section such as Admin | Other and click + Add | Subarea.
- In the Properties configuration section for the new Subarea, set the Entity value to one of your tables, or choose any of the other options relevant to your customization scenario.
- Save, Publish, and Close the site map.
