Lost Tokens Sent To Wrong Address

Sent Token to not a counterparty wallet by mistake, is there a way to get them back or are they lost in the universe of nowhereness forever ?

If you have the private key of the bitcoin wallet you can sweep the tokens back to your counterwallet using this tool https://github.com/Jpja/Sweep-XCP-Paperwallet

It went to a NON CP WALLET and their support says it is not supported. So the tokens must have been burned off at this point because no one has an answer that works.
