How can I unlock an Apple Watch with Activation Lock when I no longer have access to the original iCloud account?

I am reaching out for assistance with an Apple Watch that is currently locked due to Activation Lock. I am the rightful owner of the device, but unfortunately, I no longer have access to the iCloud account (email: j•••••@icloud.com) (yes, I do not even have the name of that email, that’s how long ago it was) that was originally used during setup.

Additionally, I no longer have the original proof of purchase or receipt. I understand this is a security measure, and I greatly appreciate Apple’s efforts to protect customer devices. However, I am hoping there might be an alternative way to verify my ownership and unlock the device.

Please let me know if there are any other options available to help me regain use of the Apple Watch. I’m happy to provide any other information I can to support my case. Please get to me asap, thank you.
