Firebase sms authorization

Hi guys, help me, please)
What steps should I take to properly connect firebase authentication to my project? So that only such authorization is possible?

Please, check this documentation : https://backendless.com/docs/android/push_push_notification_setup_androi.html

Thanks, but I do not understand how does this relate to authorization with firebase sms on others platforms

I believe this question would be better addressed to firebase support. It is their system you want to modify to hand off authorization to Backendless (if I understood correctly).

On the contrary, I want to use sms authorization from firebase for backendless. Is it possible?

I do not know anything about firebase sms authentication. I assume when it is done, it needs to execute a callback to us. Whether it does it or not, I have no idea
