You're getting downvoted to hell, but I'm going to respond anyway. The parent poster here is fully transitioning their gender. They're not cross-dressing at night, they're not "closeted trans"--they're changing their identity for their whole life, in all contexts--personal, professional, etc. Furthermore, they don't want to be known by their old identity anymore--in the parlance, that's called a deadname. So they're informing people of that happening, of who they're identifying as from now on.
