I don’t know how or why this expectation that the entire bridge crew have entire episodes devoted to them came about. They’re glorified extras who are popular. Admittedly I quite like them and would love to see them more but don’t expect it. It’s like being upset that the regular Helm officers in TNG or Ayala in VOY didn’t have more to do. Don’t get it.
No other Trek series has had A-Shift senior bridge officers who get nothing to do.
Ariam, Detmer and owokusen all seem like real interesting characters and a lot of us would rather see them get their characters expanded than seeing every episode revolve around the same 2-3 characters.
If they didn't want to do that just have a revolving door of nameless extras on the show to fill those crew spots. Don't tempt me with disfigured PTSD 12 year old super pilot Detmer and freaking cyborg lady then NOT expand those characters.
