I develop multi tenant web app.
App is cofigured to support Accounts in any organizational directory (https://learn.microsoft.com/en-us/azure/active-directory/develop/quickstart-modify-supported-accounts).
I plan to register App in AppSource marketplace "Web App" category (https://appsource.microsoft.com/en-us/?product=web-apps).
App must support "Free Trial" publishing option (https://learn.microsoft.com/en-us/azure/marketplace/determine-your-listing-type).
How to restrict access to my app only for trial organizations and organizations that bought a license?
How to check license? Or maybe Azure will not grant users access tokens for app if they have no license?
