How to add a ready-made Vue application to nuxt?

Question

Vue.js

Hello, I recently started to study nuxt and vue, I have such a question.
Making a website using nuxt.
A certain page of the site is an already assembled Vue application (html , css , js), the question is how to add this application to nuxt as a page if it accepts only vue components in pages.
Is it possible to somehow build a Vue application into 1 vue component (vue-cli), and then connect it to nuxt?
If it is somewhere in the documentation, please throw off the link, I did not find something.
