I agree with Red Queen on this one.
In PnP you'd have an active way to ask the DM for an "info-acquiring" skill check and he will tell you to roll. You know what the equivalent would be in BG3? Clicking your shovel every 2 steps to make sure you didn't just walk past some hidden treasure.
I would rather have it work passively and provide reassurance even on a fail rather than have to walk on every single cell of a grid because I don't know if I failed the check or just haven't triggered it yet.
No, it would be an Investigate Action that would search in a 18m radius. Search the area.
Which could easily just be abstracted into characters doing it everywhere automatically.
Perhaps the best way would be to just reduce the radius of a fully automated search. Teach the player to move their characters closer to the wall they want to look into. It would be the most intuitive and player convenient way, without any extra buttons, while having the feeling that you are searching.
Point remains, the
player should not know anything if the characters don't know.
