How do I use Apex private match?

Excuse me, could you possibly explain to me in detail how I can effectively utilize the Apex private match feature? I'm a bit confused on the process and would greatly appreciate some guidance. I'm hoping to be able to create my own private matches with friends and ensure that we can all enjoy a seamless gaming experience. Is there a specific set of steps I need to follow, or are there any tips you could offer to make the process easier? Thank you in advance for your help.
