You would have to decide on a data storage solution.  You could use a Sharepoint List from your PowerApp but that would result in a suboptimal user experience, as SharePoint doesn't support Direct Query.  A SQL Server database as the backend would be better because it supports Direct Query, but it comes with a (steep) additional cost as the connector is considered Premium and requires that each user of your PowerApp has such a Premium license.

If you are on a Fabric capacity you will want to consider using UDF instead - they are the go-forward technology for collecting user feedback and data write back. Overview - Fabric User data functions - Microsoft Fabric | Microsoft Learn
