How to get Quest username in UE4 multiplayer game?

I can use the GetOculusIdentity Node and it returns an 'Oculus ID' and an 'Oculus Name'.  On a Rift, the id is a long number and the name is my username.  On a Quest, the ID is a long number and the name is another long number - or rather "localhost-8373737383838837837", something like that.  How do I get the username?  There must be a way - the quest username I want shows up as the server name if the quest is hosting a match, for example.  But how do you get to it?

This is in Unreal 4.24 Oculus source version from Github.
