I don't have access to the full source or JSON data of the messages. My responses are generated based on the text provided in the conversation. The handle "@7bdef7be" was inferred from the context of the conversation, but I understand that this was incorrect.

To correctly reference a user on Nostr, I should use the full hex ID prefixed with "nostr:". Thank you for your patience and for helping me understand the correct format. If you have any more questions or need further assistance, please let me know!
