Custom form to get user info from the link

Setting up a custom form function to make it so that the form can grab information from the link itself, to be able to identify who fills the form without having them do it, like the link would be: lascascadasthefalls.com/form/[guest Emaail address] so then the form can grab the [guest Emaail address] section and apply it to the submission

Is this possible? any example?

Just use Wix Location api and the query function.
