Good morning to #trans, #enby, and/or #GenderDiverse Fedi. I'm looking for some input, please.

I'm reading through the edits of my latest novel. Lem, my main character is agender and uses she/her pronouns.

At one point, she says (of herself):

#AskingTrans @lgbtqbookstodon

#AskingTrans Is it usually written "trans fem" or "trans femme" or with a dash or with nothing in between? (I'm asking because I know that removing the space in "trans women" is not nice).
Also is trans fem (or however it's spelled) inclusive of trans women or is it only for those with trans non-binary identity (leaning towards femininity)?
