We are trying to use a form on first login to select additional information, and based upon an API call using a Flow we’d like to render a series of radio buttons to make a selection.

Would I be correct in thinking that the regular Choice component does not support dynamic values (I’ve tried inserting `{{vars.myvar}}` type syntax without any luck), and the only way to do this is with the “Custom” component that’s marked as “Add-On”?
