Proper way to implement modules || window not defined error

I’m trying to implement a vue3-scroll-spy plugin on vitesse.

On dev mode runs perfectly, but when i make a build, throws a window is not defined error.

[vite-ssg] Build for server...
vite v2.5.1 building SSR bundle for production...

 ERROR  Command failed with exit code 1.

i can use client-only and works perfectly, but how can avoid this error or integrate modules only in client mode.    I try this in vue3-scroll-spy.ts

import { registerScrollSpy } from 'vue3-scroll-spy'
import { UserModule } from '~/types'

// Scroll spy Integration
export const install: UserModule = ({ isClient, app }) => {
  if (isClient)
    registerScrollSpy(app)
}

This is the module repo: https://github.com/bennyxguo/vue3-scroll-spy#readme

on nuxt I write ssr:false and works fine, how is the proper way in vitesse?

Thanx in advance

try removing/comment out the mock option from ssgOptions on vite.config.ts file
