This editor has an Entities folder where you can add the entities and/or structures you want to use.
Right-click the Entities folder, in the Record Editor, and specify the entity or structure you want to use, through the corresponding Add <Entity/Structure>.
In this pop-up menu you will find all the entities and structures created for the module.
