Embedded form scroll issue on mobile

Hello friends.
My client wants a pop up form embedded on the site which works fine on desktop but on mobile the user is unable to scroll to reach more of the form

First button - book a free strategy meeting.

A couple of questions.
Is there a known way around this issue?

He’s able to send an embed link that has it’s own modal/pop up. Is there a way to open that if a user clicks a button? or does it need to embedded in a page?

Many thanks Alex
