As per the previous recipe, you will need a license that includes PowerApp capabilities. PowerApps are included in Dynamics 365 Enterprise Edition Plan 1 (or higher) or can be purchased independently.

From a CDS perspective, you will need an existing environment with a database containing the Feedback entity, as created in the previous recipe. Alternatively, you can use the same pattern with a different entity of your choice. Make sure you have the correct privileges (Read/Create in our example) for the entity you are manipulating.
