[AS][CC2017] Relink file in smart object layer

Hi,

I need to relink an external file, located inside a smart object layer using AppleScript.

Does anyone know if this can be done ? Currently I have ...

tell application "Adobe Photoshop CC 2017"
  tell current document
       set myLayer to my getLayerByName("Example")
       -- Relink external file located inside smart object layer
  end tell
end tell
on getLayerByName(myLayerName)
  tell application "Adobe Photoshop CC 2017"
       tell current document
       repeat with i from 1 to count layers
            set currentLayerName to (name of layer i) as string
            if currentLayerName is equal to myLayerName then
                 return layer i
            end if
       end repeat
       end tell
  end tell
end getLayerByName

Thanks
