I am trying to add a github gist to my webpage on the click of a button however the gist is not appearing.

function createGist(gistId = "bd10e846c6eae4419c3041f3da1b82a0"){
    var script = document.createElement("script");
    script.src = "https://gist.github.com/snakifyanswers/" + gistId + ".js";
    document.body.appendChild(script)    }

I am left with nothing there even though in inspect element I can see the script object.
