ReCaptcha validation on Embedded Google Form in Mobile

Site URL: https://www.errolcratt.com/book

Hello! 

I've got a google form embedded on one of the pages of my website. I use google forms rather than the squarespace forms because information submitted automatically populates on a spreadsheet and makes managing my appointments/related data easier. 

When the form is completed and the user selects "submit" a reCaptcha validation window pops up. On the mobile version of my site, the pop up appears at the top of the form, rather than the bottom where the submit button is. In order to actually submit the form, a user must click "submit", and then intuit that they need to scroll all the way up to the top of the form, and then complete the captcha validation. This is pretty clunky in terms of user accessibility, and has led to a fair bit of confusion. 

Is it possible to change where the captcha pop up appears? It would make the most sense for the pop up to become visible at the bottom of the form in the same area of the submit button on the mobile version of the page that I've linked.

Any suggestions would be greatly appreciated as I'm out of my depth on this one! :-)
