Should my 2 year old be opening doors?

This feels like a dumb question so please don't judge. I'm a FTM of a 2.5 year old who has hit all the milestones, but she can't turn doorknobs to open doors. I've never tried to teach her this because I am not eager for her to know how to do it, but I just realized maybe I'm making a mistake and I should be teaching her. Is this something you typically teach your kid to do, or just let them figure out on their own?

(The fact that I couldn't find the answer online makes me think this is a really dumb question so please be nice! Thank you!)
