How do you figure out which control UUIDs to use?

For example, how do you know that UUID_CONTROL_CHARACTERISTIC = '00010203-0405-0607-0809-0a0b0c0d2b11' was the correct control UUID to use for something?

For more advanced Govee lights that have multiple segments, do you have ideas on how to adapt this library to get a list of all of the lights, and then how to set each one individually?

I suspect more reverse engineering is needed
