Is it possible to sync a folder in the Typst webapp to GitHub?

I have a folder of greeting/birthday cards I’ve created in the Typst web app. I’d like to sync that entire folder to my greeting-cards repo in GitHub, but it seems I can only sync one Typst document at a time? And due to the requirement that the repo directory need be empty to set up a sync, I’m not actually able to sync the multiple documents I have in the directory. Would love some help to set this up if it’s possible!
