How to display native alert in Adobe Premiere pro extension

[ejaza7920015]

Hi i want to always show the native alert but when i do it in Javascript side it will look like this as shown below

In MAC it even looks even Ugly

the above alert comes when i do something like this from Javascript side

alert('Are you sure to delete')

When i do it in jsx side , it will look something like shown below

JSX side

alert('No active sequence');

Question: i always want to display native alert even from javascript side how can i achieve that

ExtendScript alerts (displayed by PPro) will display like the ScriptAlert dialog, above; JavaScript alerts (displayed by the instance of Chromium which loads your panel) will display like the JavaScript Confirm dialog, above.

@Bruce Bullis is there any way to display native dialog from javascript side (like the 2nd image)

As above; no. 
ExtendScript will always look 'native', JavaScript (CEP) will always look like the first image, above.
