Help with my karaoke set up!

As the title suggests, i’ve never done this before and i’m throwing a small party for my mum and she loved karaoke. I have a smart tv and a bose wave sound touch. I’d planned on using the apple music sing-a-long version but I have absolutely no knowledge of what kind of mic to get and how to go about connecting the system.

A little to desperate here so any help and links/suggestions would be appreciated!
