I am creating 100s of links using <links> but I am not able to do SEO for it

I am trying to create sitemaps for these links but as its dynamic, I cannot manually create a sitemap file

this the link

 <Link to={{pathname: `query/${itm._id}`, query: { id: itm._id },}} >
  <Alert className="question13">
  <h6>{itm.Name}</h6>
  </Alert>
</Link>

the corresponding route for the link is here

 <Route
exact
path="/Query/:catId"
render={(props) => (
<Query {...props} sign={userNAme} hide={SignIn} />
)}
/>

I have used helmet so that I can render dynamically each page title and description

                <Helmet>
                  <meta charSet="utf-8" />
                  <title> {itm.Name}</title>
                  <meta name="description" content={itm.Name} />
                  <meta property="og:type" content="article" />
                  <link rel="canonical" href={itm.Name} />
                </Helmet>

this is the website I am trying to do SEO for. As you can see if you open site and add a question a new url gets generated I don't know how to do SEO for each of that
