How to render Latex in Jupyter

Question

So I am trying to get Latex in my Jupyter Lab going.

If I insert this

\begin{eqnarray}
     y & = & ax^2 + bx + c \\
     f(x) & = & x^2 + 2xy + y^2
\end{eqnarray}

it gets rendered as expected

But

\begin{itemize}
    \item First.
    \item Second.
\end{itemize}

gets rendered as the text

I already installed @jupyterlab/latex extension
