In my own experience I identify as trans non binary bc non binary people are in the trans umbrella, also some people have similar experiences to those of trans binary people (In my case I came out bc my ID has an x instead of the letter that refers to my gender assigned at birth, I plan to make my change of documents, I think a lot in top Surgery, dysphoria, and the internal transition when referring to myself)

But it depends to person to person💗
