How to allow user to select own role in registration

New to Velo here, but experienced in Javascript. I’m trying to find some resources/advice on how to create a registration form that allows for the Users to select one of two available roles for my website. Upon submit, I want for the Users role to be determined automatically, without me having to go in and manually change the role. This way I can eventually show Role based content based on selection.

Thank you in advance, all help is appreciated. :sunglasses:
