KivyMD android app - problem with permission

[polak7gt]

I created a simple app for viewing my weekly meal plan. It reads the SQLite database. The app worked on my old smartphone; however, it does not work on my new Pixel 7 smartphone. The issue is that my app does not have access to the smartphone's storage, where the database is localized. It was possible to grant that access with my old smartphone; however, it is not possible with the new one. So, I have to modify my app to make it request such permission. Unfortunately, I don't know how to do that. I tried with ChatGPT, but it didn't work.

Here is my simple code, which worked on my old smartphone:
