is there a way to extract MSIs from wix4 bundle?

Hi,

Could you please advise, is there a way to extract MSIs from wix4 bundle?

I have bootstrapper application from which I need to have ability to enumerate payloads from there and extract MSIs into some temporary folder (like Unbinder().Unbind(bundlePath, OutputType.Bundle, extractedBundlePath); in wix3.
Seems bundle itself is the zip archive, so extracting "0" file from there and manually parse XML to get Payload file path and source path can solve my issue, but it looks very ugly and undocummented.
