As per @sicehice's tweet here (https://twitter.com/sicehice/status/1647773193728405505), the contents of launch_keys.txt for this sample are available at this Pastebin: https://pastebin.com/zrskCkn5 (archive: https://web.archive.org/web/20240106072638/https://pastebin.com/zrskCkn5)

If you're reading this comment and all you want is just a single set of valid launch keys to test with, you can use

mC -zmhrV -6TCy2umRXO1Nn6QNAphUGKd -h8BBVdex5GCKy

(the first entry in that Pastebin link)
