Testing the App Review Alert

Hello, we are using StoreKit's requestReview API to request App Reviews. From my understanding the app review alert will reliably appear in development builds, but only 3 times out of 365 days in production builds. We are building an app for a customer and they want to test the app to see that the app review functionality is implemented. One option is to provide them with a development build, and add their device ID to the developer portal. They can then tap a button (for example) and see the app review alert. However, this is not a scalable solution. Are there alternative ways, or other types of builds that we can provide the customer where the app review alert would reliably appear like it does for a development build?
