Greasy Fork

I have the "src" foulder of that extension. I don't know anything about coding or programming. But maybe you could work something up from it.

Folder in WinRAR: https://files.catbox.moe/gpikwq.rar

I've seen forks on github where people updated it for x.com. Don't know about recent changes tho.
This script is made for convenience with minimal features (hence the "part of its functionality" in the description") and I don't want to waste my time fixing that and adapting for MV3.

Here, use this one: https://github.com/ara303/twMediaDownloader

Note that the timeline downloader is broken since API endpoints for that, I believe, are gone, so the script is not that much different from what you are trying to find.

Question, did you managed to solve the issue where it can't download posts with multiple videos? Posts that has 2, 3, up to 4 videos?
