Seems like what counts is an enemy directly seeing you. I tried with Loki and the challenge failed as soon as I came out of invis in an enemy's field of view, even though they had no time to trigger an alarm. When using Ivara's Prowl they would become alerted after killing a nearby enemy but couldn't see me, challenge passed. So, Ivara built for min drain Prowl with a silenced primary and Covert Lethality dagger.
