In my current playthrough, Shadowheart died when she got knocked off a cliff in the Underdark, so I could not resurrect her immediately. I noticed her Mysterious Artifact on the ground, picked it up and examined it, before returning to camp and asking Withers to resurrect Shadowheart.
When I talked to her, there was no dialogue choice to mention that my character has the artifact and that it seems to be bound to her now, and Shadowheart doesn't mention it either.
I tried to use the artifact again outside the camp, with Shadowheart in my group. Astarion and Wyll both reacted to the situation, but not Shadowheart. Since she risked her life for this artifact, I would have expected a comment when it suddenly changes its owner

I have never encountered this situation before, so I do not know if it is a bug that a dialogue/interaction with Shadowheart is missing.
Does anybody know if there usually is a dialogue?
Thank you in advance!
