How to know which button has been clicked (not in handleSubmit)

[pellea]

Hello,

I have 2 buttons to handle the form.
Using form.Subscribe inside the button custom component, we have access to state like isSubmitting, ...

 <form.Subscribe
      selector={state => [state.canSubmit, state.isSubmitting, state.isPristine]}
      children={([canSubmit, isSubmitting, isPristine]) => ( 
         <Button ... />
        </>
      )}
    />

I want to have different "style" between the button clicked by the user and the others. For example to display a loading indicator only on that button and not the others.

How can I achieve this. Is it possible to pass a custom state somewhere?

Is it not possible?
