Its a Custom Web Component. Do not use the constructor directly with the new keyword. Instead, use one of the 3 following methods:

Create the Web Component and call its init method:

const myImage = document.createElement("a-image").init(config)

Or use the shorthand for it:

const myImage = createImage({
 src: "./logo.png",
 alt: "Company logo"
})

myImage.render()

Or directly declare the config inside a container component:

const myPanel = createPanel({
  title: "My panel",
  items: [
      {
          type: "image",
          src: "./logo.png",
          alt: "Company logo"
      }
  ]
})
myPanel.render()
