P: Export video keywords in the same way as photo keywords

I have over 780 drone footage clips in Lightroom, meticulously cataloged. I wanted to export them after the photos to upload them to our new online photo library (useless for tagging but essential for sharing and access control). And surprise: not a single keyword was included. I discovered that Lightroom doesn't export them, and the plugin I found doesn't work.
All we can do now is wait for a Lightroom update so we can use and share our footage, because recataloging it via the online tool would be far too time-consuming and risky to attempt.
