Support for NTT docomo fujitsu arrows tab F 02 F

Guys, hello

I'd like to root [https://www.fmworld.net/product/phone/f-02f/spec.html?fmwfrom=f-02f_index](F 02F).
As far as I understand, the android_run_root_shell does not support it at the moment. I wanted to ask how difficult would it be to add the support of this model? I mean, I know some programming and given some guidance, I would be happy to add the support myself.

Best,
Alex
