Hello and welcome

Hormones help FTM people gain a lower voice, for MTF people they may help a little but not much.
Hormones may make the voice a bit softer.
Voice training is needed.
Imo its not difficult but it takes consistent training over months.
Basically its raising the voice and practising until a higher register is available.
Singing training can help.
Its training muscles of the larynx to hold in a higher position.
Reading a book in a slightly higher voice for example, in the beginning only for a few minutes a day.
Never overstrain your voice, just stop then. Drinking enough water to moisten the throat is also recommendable.
Its possible to record the voice from time to time, and listen for effect. A few different effects can be tried, like a more breathy voice.
Resonating undertones should be avoided. Laying a hand on the chest, there should be no resonance there.
Its like moving the voice to the head...
and females often also use a bit different vocabulary ... indirect expressions like might ... and their voice has more intonation, it goes more up and down within words and sentences.
As said imo most important is persistency, a few minutes every day.
Here are a few further hints:
