Haha! Lucca, people have told me I should have done radio, too, with my deep voice!
Sometimes I get discouraged when my chest is vibrating but I think I am doing it correctly; based on my own observations, getting your voice to not vibrate in the chest is only a 'start' to training with resonance, but once you're closer or more comfortable, the chest can and does vibrate, anyway.
It's all about air flow control. Voice training was especially hard for me at first, because prior to my transition I was what you would call a mouth breather, so my nasal cavities needed to 'wake up' and do some work for once in my life, cause a whole whole lot of snot, mucus, and phlegm. But that really only lasted about the first week.
More so than just training yourself to move your adams apple up, I find it more critical to also work the muscles that move it 'back' like I think when I was training it was similar to tightening my whole neck when I first did it, because you gotta understand most of these muscles exist but have never really been used- which is why people say not to push yourself too hard with voice training at the beginning. (doing this also allows you to do the 'shelf' trick, but I have inconsistent results with achieving it most of the time)
I'm sure you're also aware that people describe feminine voices as 'sing-song' so, naturally, it helps to also sing, but you want to be careful with adjusting your natural range too much, at least at first.
For me, I listened to a Youtuber called Jenna Moreci who vlogs stuff for writers(i'm also the writer for the game I'm working on) and I sing disney or other songs; I find that my voice has the most harmony with Anna from Frozen, and Anette Olzon from Nightwish.
Also, I would search on Youtube for daily singing exercises and do some of them, too. I think that helps. It really takes time, and practice. And if you need help with enunciation I would recommend googling tough twisters for singers(one page lists like dozens of really good ones that you can practice saying and also singing)
This sound clip is a bit old now, but this is what I posted in the "Does my voice pass?" sticky awhile ago:

Good luck, Lucca!
