Show Save As Dialog Help

I am trying to show the Save As Dialog Window but running into some issues.

Open Image in Photoshop, go to File Save As and this opens the Save As Dialog.

Scenario UXP:

currentDocument = app.activeDocument

If the opened image has NOT been touched then the above code just saves the file back to where it came from.

Now, make changes to the file and use the above code and then the Save As Dialog shows, which does make some sense as some changes have been made.

Is there any way to show the Save As Dialog whether any changes have been made or not just like you can by going to File Save as in Photoshop ?
