How to submit data from Power Apps to a SharePoint list without giving users direct access?

Hi everyone,
I'm building a Power Apps app connected to a SharePoint list called "Fattura", which is located in a SharePoint site/group called "Administration".

The app allows users to fill out a form and, when they click "Submit", a new row is created in the SharePoint list.

🔒 The problem is that I don’t want to give users direct access to the SharePoint list — they shouldn’t be able to view or read any list items — but I still want them to be able to submit data through the app.

How can I solve this issue?
