window.history.pushState() does not work on URLSearchParams

Question

Hi I am trying to pass params to backend from frontend using URLSearchParams to filter a list. The filtering did not happen without reloading the page because URLSearchParams wasn't updated. I wrote code as follows by searching the answers on this website but it still doesn't update. Please tell me what is wrong.

HomeScreens.js

import React, { useEffect } from 'react';
import { useDispatch, useSelector } from 'react-redux';
import { useSearchParams } from 'react-router-dom';
import Filterbar from '../components/Filterbar';
// import PhotosnapIcon from '~/images/photosnap.svg';
import { listJobs } from '../actions/jobActions';

import './HomeScreen.scss';

export default function HomeScreen() {
  const dispatch = useDispatch();

  const jobList = useSelector((state) => state.jobList);
  const { loading, error, jobs } = jobList;

  let [searchParams, setSearchParams] = useSearchParams();

  const params = [];

  searchParams.forEach((value, key) => {
    params.push([key, value]);
  });

  const queryParams = new URLSearchParams(params);

  const url = new URL(window.location.href);
  window.history.pushState(null, null, url);

  useEffect(() => {
    dispatch(listJobs(queryParams));
    console.log(jobs);
  }, [dispatch]);

  const addQuery = (key, value) => {
    setSearchParams((prev) => [...prev.entries(), [key, value]]);
  };

  return (
    <>
      <Filterbar />
      <ul>
        {jobs.map((job) => (
          <li className={job.featured ? 'post featured' : 'post'} key={job._id}>
            <div className="post__img-container">
              <img src={job.logo} alt="photosnap" />
            </div>
            <div className="post__upper-container">

                {job.new && <span className="post__label new">new!</span>}
                {job.featured && (
                  <span className="post__label featured">featured</span>
                )}

I just needed to add searchParams in dependency array in useEffect to re-render whenever serchParams is changed. When I put queryParams in the dep array I got indefinate loop, so I was confused, but searchParams is working.

useEffect(() => {
    dispatch(listJobs(queryParams));
  }, [dispatch, searchParams]);
