How to list all available custom icons

Usually I fetched the different icons with something like.

var icons = import.meta.glob(`.././assets/*.svg`, { as: "raw", eager: true })

for (const item in icons) {
  body.innerHTML = icons[item]
  let name = item.formatx(`../assets/$V.svg`)
  let color = body.querySelector("#color")?.getAttributeNS(null, "fill") || "black"
  let size = undefined // TODO

  result.push(await icon(`${name} c-${color}`, body.querySelector("svg") || undefined))
}

But this returns

Is there a better way?

Start with the import.meta.glob custom-SVG example in the issue and inspect the repository's current custom-icon documentation or API entry points; no specific file or test is named. Determine whether the supported way to enumerate available custom icons is documented, then make the expected listing behavior and example explicit.
