Hello, lovin this project so far. Thanks for all the hard work. One question, is there any way to send additional data from the react signup form to the backend, data in addition to the form fields? I did an override on the backend API when creating a user so that it also creates that user in my hasura database. It would be awesome If I could pass some additional data in there to help with my multi tenancy. I was thinking of using the additional custom form fields in the front end to pass some extra data but that wont work if I can't make the field hidden. That would be an easy way of doing it. allowing for a hidden + default custom field on the front end that would then be available on the back.
