To implement licensing in an app, set the enableLicensing flag in the app descriptor file (atlassian-connect.json) to true. Any app intended for sale should have this flag enabled.
This tells UPM to check and report licensing status to the app. On the other hand, if you are using a app strictly for internal use or you plan to distribute it freely on the Marketplace, this should be set to false.
