How to set phabricator to where fixes are assigned back to a user?

Are you referring to Maniphest, Differential, or Audit? What is your workflow now? This question is fairly vague.

sorry all our work are going through maniphest.

Just need fixed bugs from maniphest to loop back to me so I can close them out rather than looking at the recent activity log every time due to the fact that I might miss closed bugs that are fixed.
