Extend equation editor in word with LaTeX packages for chemistry?

Question

To help students (age 14-18) who have difficulties in handwriting I have implemented a number of tools in word. I have defined macros that insert an equation using LaTeX coding. I have defined a custom toolbar and shortcuts to access these macros.
The way to use the equation editor, the tools and the macro's are described in this document (in Dutch):

This works fine for mathematical equations, but does not help for Chemistry. I would like to use extra LaTeX packages for editing Chemistry in word. Is that possible?
The LaTeX packages I would like to use are used in this project https://www.overleaf.com/read/ftbchgbzctfb

With kind regards
