BT gyro controllers for Android VR game

Hi! I'm new here... I'm a self taught learner... What I need is to make a couple of virtual hands work with gyro in the VR game, because I need to capture their movement.
For this, I'm trying to find a controller with gyroscope, which works on Unity for an Android game via with Bluetooth. I asked Nyko if their Dualies work but they've answered me they're only made for Switch. I don't have money for Joy-cons, and can't find any info about Dualshock 4 gyro working on Unity. Do any of you guys have any data about this? If not, do you know if is possible to use another cellphone's gyroscope as a controller? Thank you.

Sorry if you don't understand me... My native language is Spanish and is still hard to me to explain what I need in Spanish lol
