Typeform user feedback (Sidetab)-@typeform/embed-react library.

Hello,

I am implementing Typeform user feedback (Sidetab) in React using @typeform/embed-react library as following:

//In React I use the bellow code

<Sidetab
        id={formId}
        hidden={{
          user_id : me.id,
          name: me.first_name,
        }}
        ref={sidetabRef}
        medium="demo-test"
        buttonText="Send us feedback"
        buttonColor="#ffa366"
/>

All looks good so far, the only issue is that I have not found a way to change text colour in Button or the button size. It seems there is no fields/props in Sidetab component to change button text colour/font and button size.

Any help?
