In the jwt callback, if there's an error during the refresh token process, I'm returning the token with the error property "RefreshAccessTokenError". The error looks like this:
Error refreshing access token { error: 'invalid_grant', error_description: 'Refresh token revoked' }
How can I redirect the user to the login page which is "/" if I'm getting that error? So the user can log in again and get a new access token.

async jwt({ token, account, user }) {
      if (account) {
        console.log("New authentication, creating new token");
        return {
          ...token,
          access_token: account.access_token,
          expires_at: account.expires_at,
          refresh_token: account.refresh_token,

          user,
        };
      }

      if (token.expires_at && Date.now() < token.expires_at) {
        console.log("Token still valid, returning existing token");
        return token;
      }

      console.log("Token expired, trying to refresh");

      if (!token.refresh_token) {
        throw new Error("Missing refresh token");
      }

      try {
        const refreshedToken = await refreshToken(token);
        if (!refreshedToken) {
          throw new Error("Failed to refresh token");
        }
        console.log("Token refreshed successfully, returning updated token");
        return refreshedToken;
      } catch (error) {
        console.error("Error refreshing access token", error);
        return { ...token, error: "RefreshAccessTokenError" as const };
      }
    },

    session({ session, token }) {
      if (session.user) {
        session.user.id = token.id as string;
        session.access_token = token.access_token as string;
      }

      return session;
    },
  },
});
