Can somebody help me?

The following code does not work with sdk 33:

B4X: 
       Dim rp As RuntimePermissions
       rp.CheckAndRequest(rp.PERMISSION_READ_EXTERNAL_STORAGE)
        Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
        If Result=False Then
            Exitapp
        End If

Returns false, does not request permission.
