save-disabled trials?

Regarding 3.1.1, last bullet:


Non-subscription apps may offer a free time-based trial period before presenting a full unlock option by setting up a Non-Consumable IAP item at Price Tier 0 that follows the naming convention: “XX-day Trial.” Prior to the start of the trial, your app must clearly identify its duration, the content or services that will no longer be accessible when the trial ends, and any downstream charges the user would need to pay for full functionality. Learn more about managing content access and the duration of the trial period using Receipts and Device Check.


So, does this imply I can't have a save-disabled (but time unlimited) trial for my document-based app? It seems that a time-based trial is the only option.


Are there any apps with save-disabled trials on the store?


thanks!
