How to stop Hubspot forms adding additional scroller on Google sites

I've noticed the Hubspot form embedded on my Google sites is adding an additional scroller. When viewed on a mobile device browser, this is really confusing for an unfamiliar viewer. It's unclear where the user should hold their finger to scroll down the page.

Is there a way to have the embedded form be part of the page and scroll all at once, not two scrollers?

This is the code from Hubspot forms:

<script charset="utf-8" type="text/javascript" src="//js.hsforms.net/forms/shell.js"></script>
<script>
  hbspt.forms.create({
    region: "na1",
    portalId: "9155464",
    formId: "f6a32df3-0cdc-4c91-b71f-19fd4d623f57"
});
</script>
