How to open a dialog in App ConfigurePage (static app)?

I want open a dialog when the configure button is pressed on the manage apps page.
this is my config page

"configurePage": {
            "url": "/config.html",
            "name": {
                "value": "Configure Plugin"
            "key": "plugin-config"


<!DOCTYPE html>

    <script src=""></script>
    <script type="text/javascript">
            key: 'config-dialog',
            width: '500px',
            height: '200px'
        }).on("close", (data) => {


This opens a new page and then opens a dialog. how can dialog be opened in the current page itself?
