title: Use SurveyJS along with Nextjs
body: <p>As knows <code>NextJS</code> is using the server side rendering, I want to use <code>SurveyJs</code> with it but <code>surveyJS</code> is using some function that must be executed in client side. In my case I wanna use <code>StylesManager.applyTheme</code> but it throws an server error of <code>ReferenceError: document is not defined</code></p>
  <p>any possible way can I use to execute the <code>applyTheme</code> function in client side?</p>
