Thanks for your feedback. I don't fully understand how to use RelayPoolNotification yet, so I'm creating a client for each relay to tag events with their source. This works well for my needs. The library is excellent - fast and reliable! Thank you for your work.

Here you can find an example, but it may not be updated to the last version: https://github.com/rust-nostr/nostr-sdk-ffi/blob/ac4d6a8fb8f61b5f3ce3148a99e9f117bcbc0afc/python/examples/bot.py
I'll try add an example in the book soon.
Just tried. Work perfectly. Thank you for the hint!
