How to modify active state in RadioGroup component?

[dytra]

Hi, so I'm copying the RadioGroup example in the payment method section from this page https://ui.shadcn.com/examples/cards

I'm having trouble to modify the active state for the RadioGroupItem

So I inspect the element, and turns out it has button to toggle the state changes

But from the RadioGroup component I didn't see the button component is implemented in this component.

Any idea where does this button from ?
