Unable to restore purchase

Hello, I an active premium yearly subscription for Lightroom app on my Android phone, but I'm now unable to restore the purchase. The error message: "the purchase found could not be restored, because i has been already been claimed".

This issue might occur because the Adobe account used during the purchase was a randomly generated account automatically assigned when I installed the Lightroom app. Unfortunately, I no longer remember this account.  If it's possible to retrieve the Adobe account linked to this premium yearly subscription using my Google account? or transfer the premium yearly subscription to an Adobe account that matches my Google account?

Thank you for your assistance.
