I have an app named "Sufio" which adds a text field in the checkout where users can enter a VAT number. What I want to do is check if there is any value in the VAT number field and if user has entered any VAT number then I want to make the "Company" field as a required field. I tried to research on shopify.dev, if we can somehow access data from fields created by third party apps but it doesn't seem possible.
Thanks in advance!
