🔥 Great enhancement! Making htmlToInsert accept both a string and an async function adds a lot of flexibility — love the use of await new Promise() here.

One small suggestion: to improve clarity and prevent misuse, you could consider wrapping new Promise(this.options.htmlToInsert) in a helper or add a check for whether the function expects resolve/reject.

But overall, clean upgrade and backward-compatible. Approved 🚀
