How to use MathJax in vaadin 13

I am developing educational app using vaadin 13. I try to use MathJax.
In regular html file, Javascript
<script src=‘https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js?config=TeX-MML-AM_CHTML\’>
can be used. Then any mathematical expression can be easily written and shown on web.

I was able to use MathJax in vaadin 8 in BrowserFrame component. But I could not dynamically modify the size of BrowerFrame according to contents.

I would like to know how to used MathJax in vaadin 13.
I tried
@JavaScript(“https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js?config=TeX-MML-AM_CHTML”)
@HtmlImport(“frontend://src/views/questionlist/question-table.html”)
public class QuestionTable extends PolymerTemplate<QuestionTable.QuestionModel> implements HasText, HasUrlParameter

But I do not know where to write mathematical expression. I wrote some expressions in question-table.html file, but did not work.
Thank in avadance.
