refresh user data when changes are made to mongodb

I am new to react and MongoDB, I have this site where the user can log in and look at his detail like name…, coming from the db. I am trying to find a way to update what is shown to the client when a change is made directly from the database, or when a button is clicked refresh user data, so it shows newly updated data from the database. I am using useReducer for authentication of the user and make updates to him from the client, but I can’t find a way to update the data shown to the client. If changes are made directly from the db, the user has to log out and log back in to see the updated version of them. Again, I am very new to useReducer and have only managed to barely make it work from what I could find, but I can’t find this particular problem I have anywhere. If someone could help, I greatly appreciate it.
Tell me if you need more context or any other file.

My AuthContext file with useReducer

import React from "react";
import { createContext, useEffect, useReducer } from "react";

const INITIAL_STATE = {
  user: JSON.parse(localStorage.getItem("user")) || null,
  loading: false,
  error: null,
};

export const AuthContext = createContext(INITIAL_STATE);

const AuthReducer = (state, action) => {
  switch (action.type) {
    case "LOGIN_START":
      return {
        user: null,
        loading: true,
        error: null,
      };
    case "LOGIN_SUCCESS":
      return {
        user: action.payload,
        loading: false,
        error: null,
      };
    case "LOGIN_FAILURE":
      return {
        user: null,
        loading: false,
        error: action.payload,
      };
    case "LOGOUT":
      return {
        user: null,
        loading: false,
        error: null,
      };
    case "UPDATE_USER_DATE":
      const updatedUser = { ...state.user };
      updatedUser.activeUntil = action.payload;
      return {
        ...state,
        user: updatedUser,
      };
    case "UPDATE_USER":
      const updateUser = { ...state.user };
      return {
        ...state,
        user: updateUser,
      };
    default:
      return state;
  }
};

export const AuthContextProvider = ({ children }) => {
  const [state, dispatch] = useReducer(AuthReducer, INITIAL_STATE);

  useEffect(() => {
    localStorage.setItem("user", JSON.stringify(state.user));
  }, [state.user]);

  return (
    <AuthContext.Provider
      value={{
        user: state.user,
        loading: state.loading,
        error: state.error,
        dispatch,
      }}
    >
      {children}
    </AuthContext.Provider>
  );
};

where i am trying to make the update happen

import React, { useContext } from "react";

export default Userinfo;

in particular ->

 const refreshUser = async () => {
    try {
      dispatch({ type: "UPDATE_USER" });
    } catch (err) {
      console.log(err);
    }
  };
