At which stage of the design process do we use ‘How Might We’ and ‘As a user’ statements

This might seem pretty obvious to some. i'm a self learned designer i'm always trying to figure out and fill my knowledge gaps.

At which stage of the design process do we use.

  1. 'How Might We' statement
  2. 'As a user' statements

From my understanding so far, HMWs are used to spark creative thinking for ideation sessions and As a user statements are used for user stories to be designed and developed.

Am i correct on this and where else can these be used? of course no design process is the same but i'm curious to know how and where you use it.
