  if (status == PermissionStatus.Granted)
  {
      var fileResult = await FilePicker.PickAsync(new PickOptions
      {
          FileTypes = FilePickerFileType.Pdf,
      });

      if (fileResult != null)
      {
          pdfFileName = Path.GetFileName(fileResult.FullPath);
          pdfBytes = File.ReadAllBytes(fileResult.FullPath);
          IsPdfVisible = true;
      }

      {
          var requestStatus = await Permissions.RequestAsync<Permissions.StorageRead>();
          if (requestStatus == PermissionStatus.Granted)
          {
              var fileResult2 = await FilePicker.PickAsync(new PickOptions
              {
                  FileTypes = FilePickerFileType.Pdf,
              });

              if (fileResult != null)
              {
                  pdfFileName = Path.GetFileName(fileResult2.FullPath);
                  pdfBytes = File.ReadAllBytes(fileResult2.FullPath);
                  IsPdfVisible = true;
              }
          }
          else
          {
              await ToastHelper.ShowToast("Please grant permission to access storage..");
          }
      }
  }

This is my code ,I am using .NET MAUI with .NET7,My android:targetSdkVersion="33", I want to pick pdf from device ,In my android12 device all are working good but what permission do we use for android 13, When i use ReadMediaImage permission instead of Storage read i get an error (doesn't exists in the current context).

Hello,

After Android 13, Google further refined the permission management of external storage.

Please refer to File picker for more details.

If your app targets Android 12 or lower, you must request the READ_EXTERNAL_STORAGE permission. If your app targets Android 13 or higher and needs access to files that other apps have created, you must request one or more of the following granular permissions instead of the READ_EXTERNAL_STORAGE permission: READ_MEDIA_IMAGES READ_MEDIA_VIDEO READ_MEDIA_AUDIO
