Retrieving AAM UUID from AEP 5 SDK to set in context data variable

Hi,

How do we retrieve AAM UUID from AEP 5. The client wants to retrieve this ID and set it in a context data variable for both Android and IOS.

I understand that the method to do this with Adobe SDK 4 was getallidentifiersasync. What is the method that we can use for AEP 5. is it identity.getidentifiers? 

If yes how do I then set the AAM UUID in a context data variable?

Thanks and regards
