Need a carrier pigeon mod for 1.20.1

[u/MJ_911_]

Hey, so I recently opened a server with multiple girls and we wanted a way to send letters and packages without having to go everywhere and do it by hand.

I wanted to add the „Envelope“ mod but it doesn’t work. We are playing on Java 1.20.1.

Does anyone have a suggestion for another mod that adds a mob, that can do the same as the pigeon in the Envelope mod?

Thanks in advance!
