[VSCode] Plot pane is not working for PGFPlotsX

Hi everyone, I’m trying to plot some graphs on the plot pane on VSCode.
I have toggled on the Use Plot Pane option as below:

Unfortunately, everytime I type td or display(td) in the Julia REPL after the following code, it opens a pdf reader (preview) and display the figure on it instead of the plot pane. Can anyone help me fix this?

Here is the MWE:

using PGFPlotsX

push!(PGFPlotsX.CUSTOM_PREAMBLE,
    raw" \usepackage{bm}")

td = TikzDocument(raw"""
\begin{tikzpicture}
    \begin{axis}[
        xlabel=$\bm{x}$,
        ylabel=$y$
    ]
    \addplot[smooth, mark=*, blue]
    table[row sep={\\}]
    {
        0 2 \\
        2 3 \\
        3 1 \\
    };
    \addlegendentry{Case 1}

    \end {axis}
\end{tikzpicture}
""")

And here’s my environment:
