great extension,but how to format .es file

[godhelpjun]

when I press alt+ shift + f
there is no formatter for .es file

or how could I use jsonc extension formatter?
also,I try to add settings.json
"[es]": {
"editor.defaultFormatter": "vscode.json-language-features"
}
but,no luck.I don't have much time for try something more,so I'm here to ask,thanks,bro.
