I've been trying to use the latex `annotate-equations`

package with quarto (see https://github.com/lpembleton/annotate-equations/blob/main/annotate-equations.qmd)

Here is the first bit of the example:

```
---
title: "Prediction Equations"
format:
beamer:
header-includes:
- \usepackage{annotate-equations}
---
## Mean Prediction Standard Error
$$
s_{\bar{y}_p} = \sqrt{
\eqnmarkbox[green]{see}{s^2}
\left [
\eqnmarkbox[blue]{b0}{\frac{1}{n}} +
\eqnmarkbox[purple]{b1}{\frac{(x_p - \bar{X})^2}{SS_{X}}}
\right ]
}
$$
\annotate[yshift=-4em]{below,left}{see}{Residual standard deviation} \annotate[yshift=1em]{left}{b0}{Standard error of intercept} \annotate[yshift=1em]{right}{b1}{Standard error of slope}
```

I can run this on my desktop (both MacOS and Linux), but only after downloading `annotate-equations.sty`

from CTAN and installing it in a local `texmf`

directory. However, I would like to use this on my posit.cloud account as I'm using it for my students when I'm teaching. How would I go about installing a latex style file on posit.cloud?
