// do your manual work here

/* continue automated stuff */

You can trigger continuation with.

let element = document.createElement("div");
element.className = "trigger-element";
element.style.display = "none";
document.body.appendChild(element);

((s)=>{
let element = document.createElement("div");
element.className = s;
element.style.display = "none";
document.body.appendChild(element);
})("trigger-element"); // change name here

Apparently I wrote notes twice. TODO merge.
