You need to of player for at least 30 minutes and 4 rounds of the game then you can apparently invite 2 friends.

I did all that and was going to invite 2 rando's from here but the invite link just goes to their website, and instead of any referral link or key or anything, the only option was to sign up for the playtest on Epic.... So they either removed the invite friend thing, or something is broken.
