我有一个App在React. 这个应用程序有两个tabs在first tab我正在显示的列表中chated users和在second tab我正在显示的所有registerd contacts. 选项卡按预期工作。现在我的问题是当用户在时second tab，如果他clicks在任何用户上。它应该显示chat tab。我正在使用它npm package来创建tabs react-tabs。 在此处输入图像描述

// chatsection.js : 聊天组件和注册联系人的父组件

import React, { useState } from "react";
import { useDispatch, useSelector } from "react-redux";
import "./Style.css";
import { Tab, Tabs, TabList, TabPanel } from "react-tabs";

import Allcontacts from "./Allcontacts";
import ChatedList from "./ChatedList";
import { setTabPane } from "./actions";
import "./Style.css";
const ChatSection = (props) => {
  const dispatch = useDispatch();
  const tab = useSelector((state) => state.tab);
  console.log("tab", tab);
  return (
    <div className="">
      <Tabs>
        <TabList style={{ display: "flex" }}>
          <Tab
            onClick={() => dispatch(setTabPane("chat"))}
            className={` ${tab === "chat" ? "abc" : "1"}`}
          >
            Chats
