How to 'reply done' in Gerrit when I address people code review comment

gerrit

Solution

After you have added your comments to the files you will need to either go and do a 'Review' or 'Add Comment'. This will then also publish your draft comments.

Problem

When using Gerrit review, I want to 'reply done'. So I click 'Reply Done' button. But it is in 'draft' state? How can I submit the 'Reply done'?
