spring boot and react login with facebook - spring

Question

I have spring rest api and react frontned application. I want to facilitate user to authenticate with facebook. After successful authentication i use facebookId to check if that user is in my database, if he isn't i create a user and save him. It's the only way to create accounts in my application. I used this tutorial to create authentication, and it's works fine...
But two days ago i decided that i want to connect my backend with frontend and I am unable to send request to protected endpoint. When i do it, my request is redirected to /connect/facebook(with OPTIONS request method - have no idea why) and nothing happen.
I read about that i should generate tokens, but I have no idea how to associate it with facebook, and I don't even know if it is a good approach.
edit.
