WebXR change textcontent of START AR button

Hi,

I am trying to change the textcontent of the AR Button that gets spawned when I am running this code:

const arButton = arButtonContainer.appendChild(
  ARButton.createButton(
    renderer,
    {
      optionalFeatures: ['dom-overlay', 'dom-overlay-for-handheld-ar'],
      domOverlay: { root: document.body },
    }
  )
) as HTMLButtonElement;

I tried setting the text with this:

arButton.textContent = 'bla';

But it doesn’t work. Also styling the button was kinda weird, since I had to mark everything i did with !important

How can I change the textcontent of that button?

Thanks!
