Hey there @creedon,
I have a similar question but I can't seem to figure the code modification to apply it to my website.
I also have a bilingual website (FR/EN). I am wondering how to change First And Last name to Prénom and Nom. I wanted to add an address field too but I ended up removing it because I just can't figure out how to edit the form. Address for Adresse, remove State for Province, etc.
Here's my website :
