> An "incapacitated" creature can't take actions or reactions. (PHB 290)

Meaning that you can still move. But what about "interactions"?
Page 190 of the PHB describes examples you can do "in tandem with your movement and action", it also mentions "You can interact with one object of feature in your environment for free".

It seems that an "Interaction" is distinctly different from an "Action" or a "Reaction".

Are you still allowed to do (one) interaction on your turn when incapacitated?
