RM Bridge: what IR data to send for iRobot?

I’m using RM bridge and have an iRobot, which I believe could be controlled through its own IR remote. I don’t have a remote, so I’m trying to figure out what IR data I need to send to achieve some specific command (in the “data” field in RM Bridge). Someone was able to achieve this through an Arduino:

There’s also a protocol documentation here:

Any ideas would be helpful. Thanks!

Additionally, it would be great if someone could help me understand the “data” field of RM Bridge. I tried learning the power button for my TV remote two times and get different data fields:



So trying to reverse engineering the protocol would be quite a challenge.
