Can someone on leave of absence get their extention papers from an online doctor?

I'm currently on leave of absence (休職) from my work due to long ignored mental health issues. It's been helping me a lot to spend time back home overseas, but I already am expected back in Japan this week in order to see a doctor about getting the extension papers that my company wants for my continued absence.

Does anyone know this could be handled remotely through any specific clinics (specifically for mental health)? I really am not ready to end up back in my room in Japan right now, which is why I think this may be the only time I extend my absence before quitting. In any case, if anyone has handled a similar situation, please let me know. Thanks for reading.
