Sorry, I'm afraid I don't understand your question.
The Guida app (2021 sponsor version) was sold out on the 2021 campaign, and it's a Key request version.
Guide app Lite is a new version and on selling on itch.io, and it doesn't need to require the key.
as the Guida app (2021 sponsor version) already sold out in 2021, so it's not able to provide keys anymore.
I hope this can answer your question, sorry for the confusing. :/
