 ### User Data
 
 Every peer has its own user data, which is a byte array (`[UInt8]`). This data is synced automatically, which allows storing of arbitrary information for each individual peer and even globally for the room if needed. Peers can update their own user data at any time, even before joining a room to specify the initial user data value. For convenience, we're providing a set of helper functions in `OdinCustomData` to handle user data conversion:
