##         Note: Depending on the export size and your upload speed, it could take 10 minutes or longer for each archival.
##         Note: This script requires GAM, https://github.com/GAM-team/GAM
##         Note: This script can't be used with GAMADV-XTD3, https://github.com/taers232c/GAMADV-XTD3/wiki/Vault with its current syntax, even though it also supports Vault.

Nice!

Zoë Kelly obviously did all the magic, I just adjusted the language, and added the delete export process.
