How to use the next-auth/client.NextAuth.providers function in next-auth

static async getInitialProps({req, res, query}) {

    // If passed a redirect parameter, save it as a cookie
    if (query.redirect) {
      const cookies = new Cookies((req && req.headers.cookie) ? req.headers.cookie : null)
      cookies.set('redirect_url', query.redirect, { path: '/' })
    }
