Prerender-spa-plugin, how to give prerenders only for the required routes?

Question

JavaScript

Good afternoon.
Tell me about prerender-spa-plugin + vue-cli. I make pre-renders, for example, for two pages '/', '/about'. That is, dist is now index.html about.html app.html. From the server, I give all the statics like this app.use(express.static('/dist')). While there were no pre-renders, index.html was picked up and then vue-router was routed. Now, for a request of any kind /some/page, this pre-rendered index is always given first (although it is needed only for routes '/' '/index' and search engines, probably). At the same time, I do not get the /about - about.html route. The finished index.html is also given. How can I set up such routing in which index would be given only for the necessary routes and the same with about?
