Configuring major mode issue

[tkossak]

Hello, I read the docs but still have problems configuring major mode for python. I want to add keybinding: SPC m = u should run command ruff.executeFormat (only for python buffers). How do I do it? I tried different things eg:

    "whichkey.bindingOverrides": [
        {
            "keys": ["m.=.u", "languageId:python"],
            "name": "Format",
            "type": "command",
            "command": "ruff.executeFormat",
        }
    ],

or

    "whichkey.bindingOverrides": [
        {
            "keys": ["m", "languageId:python", "=", "u"],
            "name": "Ruff Format",
            "type": "command",
            "command": "ruff.executeFormat",
        }
    ],

But nothing works - the u / "Ruff format" is not shown in SPC m = submenu for python buffers.
