What should be the best practice to assign user id for a conversation in Oracle Digital assistant

While extracting insights/conversation logs from oda ,our customer wants valid username to be present as part of column USER_ID so that they can identify the conversation.

if we pass some user name as part of initUserProfile:{profile:{}} then also some random user id is getting populated in extracted logs. Using which it wont be possible to identify the customer.

When we pass user id as part of chatWidgetSettings = {} then user id is getting populated and we are able to identify the conversation.

Based on this we would like to know the recommended approach.
