How can I show privilege escalation window on button "Repair"?
    <Control Id="RepairButton" ElevationShield="yes" Type="PushButton" X="40" Y="118" Width="80" Height="17" ToolTip="!(loc.MaintenanceTypeDlgRepairButtonTooltip)" Text="!(loc.MaintenanceTypeDlgRepairButton)">
      <Publish Event="Reinstall" Value="ALL" />
      <Publish Property="WixUI_InstallMode" Value="Repair">1</Publish>
      <Publish Property="TYPE_DESCRIPTION" Value="repair">1</Publish>
      <Publish Property="TYPE_DESCRIPTION2" Value="repair">1</Publish>
    </Control>
