paid version of Automate on device without Google account

[Alex]

I have installed my paid version of Automate to a Samsung device  without Google account. .

How can authorize it as the paid version?

I guess you can not:

"Premium is unlocked by a single in-app purchase which is owned by the Google account used during purchase. All devices registered with the purchasing account will have the Premium upgrade."

See https://llamalab.com/automate/doc/premium.html

I would be interessted to buy a premium version without Google Play too.
