I'm trying to get ejs completion, But its not working as I expected. this is my coc-settings.json

{
    "html-css-support.enabledLanguages": [
        "ejs",
        "html",
        "vue",
        "blade",
        "htmldjango",
        "typescriptreact",
        "javascriptreact",
    ],
}

How can I do it ? I've searched across the web but didn't find any solution!
