How to insert latex into confluence page?

I have some equations that I need to incorporate into a confluence page. How do I do this in confluence?

Even if I have to use markdown, that is fine. but I do not see a way to do that.

I see this post: Plugin exporting Jira Confluence page(s) to LaTeX

But that is for export to LaTeX, whereas I want to go the otherway: I want to inject LaTeX into a confluence page. How do I do that?

I tried this: https://hiltmon.com/blog/2017/01/28/mathjax-in-markdown/. But even the eaxmples in that page do not work.

Thanks.
