How can I show hide my logout button based on authentication without using Redux?

With the code below, the logout button will only show if I refresh the page upon being successfully being logged in. The functionality works as intended, so no issues there.

Furthermore, I'd like to show the logout button on the navbar upon the user successfully logging in without refreshing page.

I've tried many ways to solve this but to no avail.

During my research, I came across something called Redux Persist but I'm unsure if it's worth using it in this scenario. Is there a way I can handle this without using Redux?

I'm open to code improvements/suggestions of my code. Thanks in advance.

import { Navbar, Nav, Container, Button } from 'react-bootstrap';
import axios from 'axios';
import { useHistory } from 'react-router-dom';
import {useEffect, useState} from "react";

const NavBar = () => {

    let history = useHistory();
    const [loggedInUser, setLoggedInUser] = useState("");

    useEffect(() => {
        const loggedInUser = localStorage.getItem("loginToken");
        console.log(loggedInUser);
        setLoggedInUser(loggedInUser);
    });

    const logout = (e) => {
        e.preventDefault();
        const headers = {
            "Accept" : "application/json",
            "Authorization" : `Bearer ${localStorage.getItem('loginToken')}`
        };
    
        axios.post('http://website.test/api/logout', null, {headers})
            .then(res => {
                console.log(res);
                if(res.status === 200) {
                    localStorage.clear();
                    return history.push('/');
                }
            }).catch(err => {
            console.log(err);
        });
    };

    return (
        <>
            <Navbar bg="dark" variant="dark">
                <Container>
                    <Navbar.Brand href="#home">Navbar</Navbar.Brand>
                    { loggedInUser ? <Nav className="me-auto"><Button onClick={logout}>Logout</Button></Nav> : null }
                </Container>
            </Navbar>
        </>
    );
}

export default NavBar;

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
