Remove Add Group Button

[jnedley75]

I've looked and looked but maybe I'm missing something.

Is it possible to remove the Add Group button from the builder? If so, where do I make that customization at?

settings.renderButton = (props) => {
  if (props!.type == 'addGroup' && SHOULD_HIDE_ADD_GROUP) {
    return <></>
  }
  return <Button {...(props as any)} />;
}
