Extending length of embed code window for Square Appointments to avoid scrolling

I'm wanting to extend the length of this embed code window on my appointments page so the user doesn't need to scroll inside the embed box. https://www.dabacosunset.com/appointments

Here is the code for my Square Appointments widget:

<!-- Start Square Appointments Embed Code --><script src='https://squareup.com/appointments/buyer/widget/xyebg07msxvrvf/LWJ85SMWBNQYB.js'></script><!-- End Square Appointments Embed Code -->

I'd really appreciate any help with this one.

With this case you can increase iframe height by using this code to Custom CSS box

iframe[src*="squareup"] {
    height: 700px !important;
}
