I don't think it is possible . Since Firebase will return a UID that is associated with a particular user.

I read the docs getIDToken

Unless you have stored the passwords & emails of all the users who registered, then you can request the UID one by one and store them in an array.Then you can do a Random function based of the length of the array.
