How to auto save file in VSCode on Esc when using Vim extension?

I wonder, how can I save current file automatically in VSCode after leaving insert mode in Vim by pressing Esc key?

Replacing <Esc> with <Esc>:w<Enter> works, but this is probably a slightly more elegant solution (if you have other save commands you'd like to run for example).

    "vim.insertModeKeyBindingsNonRecursive": [
    {
        "before": [
            "<Esc>"
        ],
        "after": [
            "<Esc>"
        ],
        "commands": [
            "workbench.action.files.save"
        ]
    }
],
