If you are interested in doing any further cleanup of this component, here are some suggestions which you can put in an additional PR:

• use useTranslation hook instead of withTranslation HOC
• use react-redux hooks instead of connect HOC
• access location from useLocation react-router hook
• access browserHistory from useHistory react-router hook
• turn the verificationTokenFromLocation function into a useMemo verificationToken variable
