Access the "Email" input of wix-pay popup?

[Daniel_Kazak]

Hey all, would like to know if anyone have achieved this before?

On my checkout page users fill in their email, and when they click the checkout button the following sequence occurs:

• 1. Generate login token for email
• 2. Log user in
• 3. checkout.startOnlinePurchase() Calls a wix pay popup window

Now, my question is:
Is there a way to pre-populate or access the email input element of that popup?
Since the user have already provided the email in the prior step, i would love to have the email already filled when the popup comes up (or at least, populate it somehow using the dom)

Thanks
