>Solution :

Unfortunately, this will not work as you need to specify an ID for the button and apply some styling.

To achieve what you are trying to do, you need to do the following:

1. Create the button element using JavaScript and set the ID and style properties.
2. Add the button to the page using JavaScript.
3. Add an event listener to the button to handle any user interactions with the button.

For example:

let btn = document.createElement("button");
btn.id = "iabcc4f6ccb66734d26a4c190c889867d061";
btn.style.display = "block";
btn.innerHTML = "Continue";
document.body.appendChild(btn);

btn.addEventListener("click", function(){
    // do something here
});
