@KapilJ your solution is right now the best solution, I think. Probably
the ideal solution would be if we could implement the `CreateComment`
resolver in such a way that it is doing eager loading of the
`comment->post->author` relationship and resolving a commment object
which has the required objects all set. Then you wouldn't have to
refetch all the stuff.
But I think this is OK for now 👍
I think it makes more sense to update an existing notification in place.
Ie. if there was already a notification, just mark it as unread so it
ends up in the recipient's notification list again.
