Couchbase user name not getting displayed in UI

I am using CB 4.6.3 community edition. After login into CB UI using Administrator or any other user, nowhere in UI I can see logged in user name. Anyone help me how to enable it.

Hi Nittejoy,
Thanks for using our product.
About displaying current user logged in UI, it only supports from Couchbase Server 5.x.x (5.0.0, 5.1.0 …)
If you have any question, drop me a line to thuan at couchbase dot com
