How can i add my google web app project into my wix site page?

i have a project in google app script. i want to use it in my wix web page. with Iframe it works but it is not effective at page response and mobile version.

It’s too general question because we know nothing about your app, but if you have a Wix premium account you should either consider using a custom element or adding it to the tracking section (in the dashboard).
