Cheapo Katex linked list

Sometimes you have to use Katex to show formulas in your presentation/webpage. And sometimes you have to go a bit deeper, and show a linked list with Katex. There might be a “correct” way to do that, but I just wanted a quick solution for the problem.

\boxed{ \hspace{0.1em} 12｜\bullet \>}\hspace{-0.5em}— \hspace{-0.5em}\longrightarrow \hspace{-0.3em} \boxed{ \hspace{0.1em} 88｜\bullet \>}\hspace{-0.5em}— \hspace{-0.5em}\longrightarrow \hspace{-0.3em}\boxed{\mathrm{X}}

it should output something like

you can replace the 12 and 88 with the values you want/need.
