How to link moca id to nine chronicles?

Could you please provide a step-by-step guide on how to LINK my MOCA ID to Nine Chronicles? I'm a bit confused about the process and would appreciate it if you could explain it in simple terms. I'm assuming it involves going to the Nine Chronicles website or app, but I'm not sure what to do next. Could you walk me through the entire process, including any potential roadblocks or issues I might encounter along the way? Thank you in advance for your help!
