Karabiner-Elements complex_modifications rules

In mac, hitting ctrl key is very hard. So, I consulted with gemini and he offered that I map space to ctrl key. So whenever is it hit alone, it is space. In combination with other keys, it is ctrl.

{
    "description": "Post space is pressed alone, left_ctrl otherwise",
    "manipulators": [
        {
            "from": {
                "key_code": "spacebar",
                "modifiers": { "optional": ["any"] }
            },
            "to": [{ "key_code": "left_control" }],
            "to_if_alone": [{ "key_code": "spacebar" }],
            "type": "basic"
        }
    ]
}

I don’t use this anymore. It was very annoying. I mapped my right command for right control.
