How to configure Atom to show LaTeX in Markdown Preview (Win10)?

Question

Markdown

Began to study the above tags.
Several sites that talk about the Markdown + LaTeX link say that the following code should be converted to a LaTeX formula. This does not happen to me and the preview shows the code as it is.
TeX Live and the language-latex and markdown-preview-enhanced Atom packages are installed.
$$ ax^2+bx+c=0 $$
What am I doing wrong?

Answer 1

The tool-bar-markdown-writer gave me two different Preview modes. Dark mode is opened by a button. Light mode is opened by a key combination.
I would be grateful if someone could explain how this could happen.

Answer 2

language-latex is just syntax coloring for LaTex.
Everything works with the second plugin on Linux.
