How to set up redirect in docusarus via plugin @docusaurus/plugin-client-redirects

Question

In my docusarus page I'd like to set up a redirect:

1. from example.com/docs and example.com/changelog
2. to example.com/docs/intro/ and example.com/docs/changelog/ respectively

I installed the plugin @docusaurus/plugin-client-redirects and I created the following entry

      [
        '@docusaurus/plugin-client-redirects',
        {
          redirects: [
            // /docs/oldDoc -> /docs/newDoc
            {
              to: '/docs/',
              from: '/docs/intro/',
            },
            {
              to: '/changelog/',
              from: '/docs/changelog/',
            },
          ],
        },
      ],

But I still get Page not found.
