How do I enable stylistic sets for FiraCode in Godot Engine Code Editor?(And also, the text is not connected there, too)

Here is the page that should tell me, and everyone else how to do it, but you know, nobody can do everything.
So, I decided to ask this question.
How do I enable them in Godot Engine?
This should surely be possible, right?

Also, the thing I heard is called "typographic ligatures" does not work there, for some reason.

Not necessarily. Support depends on a program. For ligatures in code editors and terminals, there’s a compatibilty list in the README. For stylistic sets, support is even more scarce — almost nobody supports them fully.

If you figure out how to enable ligatures or ss in Godot, please report back, I’ll add them to the compatibilty list.

Hello.

To enable font ligatures in Godot Engine's script editor (4.1.1).

In Editor -> Editor Settings menu, then in Interface -> Editor section:

• In Code Font select the font's file
• Then in Code Font Contextual Ligatures dropdown select:
  • Enabled to enable ligatures
  • Use Custom OpenType Feature Set to enable SS
    • In Code Font Custom OpenType Features place the SS codes separates by , without quotes or spaces: ss01,ss02,ss03,ss04,ss05,ss06,zero,onum
