What do i send back for a service request?

Hello, I unfortunately have to send my switch 2 back to Nintendo for a replacement because my screen went out. I tried to Google it and scoured the FAQ but couldn't find the info. do I need to include everything with the console? like the dock and charger? or just the console and joy cons? I don't want to include the dock and stuff if they're only going to be sending a console back, and I don't want to get in trouble for not including it if I'm supposed to. Thank you for any info!
