Support for mhchem both inline and at export

[redoxmatlab]

Hello,

I wish to request support for mhchem package (https://mhchem.github.io/MathJax-mhchem/).

This package is critical for technical writers. I have tried to add the equation below but it could not be exported correctly into PDF since mhchem is not supported.
$\ce{CH4 + 2 $\left( \ce{O2 + 79/21 N2} \right)$}$

The same applies to LaTeX expressions such as (this one below is from Typora website):

$$ \begin{align*} y = y(x,t) &= A e^{i\theta} \\ &= A (\cos \theta + i \sin \theta) \\ &= A (\cos(kx - \omega t) + i \sin(kx - \omega t)) \\ &= A\cos(kx - \omega t) + i A\sin(kx - \omega t) \\ &= A\cos \Big(\frac{2\pi}{\lambda}x - \frac{2\pi v}{\lambda} t \Big) + i A\sin \Big(\frac{2\pi}{\lambda}x - \frac{2\pi v}{\lambda} t \Big) \\ &= A\cos \frac{2\pi}{\lambda} (x - v t) + i A\sin \frac{2\pi}{\lambda} (x - v t) \end{align*} $$

Any ideas?

Many thanks.

Solving this myself. See below for whoever interested.

\begin{aligned} y = y(x,t) &= A e^{i\theta} \\ &= A (\cos \theta + i \sin \theta) \\ &= A (\cos(kx - \omega t) + i \sin(kx - \omega t)) \\ &= A\cos(kx - \omega t) + i A\sin(kx - \omega t) \\ &= A\cos \Big(\frac{2\pi}{\lambda}x - \frac{2\pi v}{\lambda} t \Big) + i A\sin \Big(\frac{2\pi}{\lambda}x - \frac{2\pi v}{\lambda} t \Big) \\ &= A\cos \frac{2\pi}{\lambda} (x - v t) + i A\sin \frac{2\pi}{\lambda} (x - v t) \\ \end{aligned}
