I am building an application (APRS <-> Meshtastic gateway), that would significantly benefit from being able to send tabpback messages. For example, a tabpback message of thumbs up could signal that an APRS message was acknowledged on the other side of the gateway. For this I understand that I need to supply a replyId and emoji.

Unfortunately mesh_interface.py only supports sending text messages. I would value either a tabpack method, or sample code for how I can create and send my own via data/protobuf.
