import React from 'react';
import { Grid } from "@mui/material";
import SideMenuBar from '../sidemenubar/SideMenuBar';

import {BrowserRouter as Router, 
    Routes, Route,Navigate,Link} from 'react-router-dom';
class Test extends React.Component{
    render(){
        return (
            <Grid container>
                <Grid item md={4}>
                    <SideMenuBar />
                </Grid>
                
                <Grid item md={8}>
                    <HomePage />
                </Grid>
                
            </Grid>
        )
    }
}

export default Test;

If you want to render a sidebar on every route/page then I suggest:

Using Layout Wrapper Component and Outlet

Create a layout container component that renders the Sidebar component and an Outlet into the respective grid columns. Render the page routes nested into the layout.

import { Outlet } from 'react-router-dom';
import SideMenuBar from '../sidemenubar/SideMenuBar';

const PageLayout = () => (
  <Grid container>
    <Grid item md={4}>
      <SideMenuBar />
    </Grid>    
    <Grid item md={8}>
      <Outlet /> // <-- nested routes rendered here
    </Grid>     
  </Grid>
);

index.js

<Router>
  <Routes>
    <Route path="/" element={<PageLayout />} >
      <Route index element={<Login />} />
      <Route path="/api/v1/app/userHome" element={<UserHome />} />
      <Route path="/api/v1/app/schedule" element={<Scheduler />} />
      <Route path="/api/v1/app/myclassroom" element={<Classroom />} />
      <Route
        path="/api/v1/app/myassignments"
        element={<Assignment />}
      />
      <Route path="/api/v1/app/mymeetings" element={<Meeting />} />
      <Route path="/api/v1/app/viewreports" element={<ReportCard />} />
    </Route>
  </Routes>
</Router>

Using Wrapper Component and children Prop

An alternative would be to have the PageLayout component render its children instead, and wrap the Routes component.

const PageLayout = ({ children }) => (
  <Grid container>
    <Grid item md={4}>
      <SideMenuBar />
    </Grid>    
    <Grid item md={8}>
      {children}
    </Grid>     
  </Grid>
);

index.js

<Router>
  <PageLayout>
    <Routes>
      <Route path="/ element={<Login />} />
      <Route path="/api/v1/app/userHome" element={<UserHome />} />
      <Route path="/api/v1/app/schedule" element={<Scheduler />} />
      <Route path="/api/v1/app/myclassroom" element={<Classroom />} />
      <Route
        path="/api/v1/app/myassignments"
        element={<Assignment />}
      />
      <Route path="/api/v1/app/mymeetings" element={<Meeting />} />
      <Route path="/api/v1/app/viewreports" element={<ReportCard />} />
    </Routes>
  </PageLayout>
</Router>
