How can we host Blazor Server Side and Web Assembly together as one application?

Need some help here.So we are in process to take Blazor as our front-end framework but I am stuck on a very small thing.First here is the requirement:

1. We need a SSR website, where we can show the list of the products and their details etc. It should be SSR for the SEO purpose.
2. We need a backend management app, on which we can build a backend app where users can add/edit/delete the products.

The thing we wanna build is

1. On root URL, we need all the SSR content like www.example.com, www.example.com/product/xyz. All pages will be SSR. I believe we can handle this by making Blazor Web App (Server) and use the SSR interactive mode.
2. The issue comes here. We want to access the backend web assembly app on the URL www.example.com/app. The app should be loaded when we call this URL and everything should just work under this app. Is this possible?

Any help or tutorial will be highly appreciated.
