For scientific/technical users, it is immensely helpful to be able to use mathematical symbols/equations in work packages and Wiki pages. I would imagine MathJax would be simple to add (link: [https://www.mathjax.org/](https://www.mathjax.org/)), or more conveniently, the CKeditor can use MathType ([https://ckeditor.com/mathtype/](https://ckeditor.com/mathtype/)).

Or maybe implement this as a plugin? Begin of the insertion

> **Acceptance Criteria**
>
> * In the Wiki page editor there should be a toolbar button to input mathematical equations. Upon clicking the button a popup filed appears allowing inputting the equation in the TeX language. Once input within the text clicking on the equation would allowing editing the TeX source equation with the same pupup used for input. All this functionality is already implemented as CKEditor 5 plugin
