And after that, you can run the project and check the functionality of this endpoint.
The main idea is that:
1) GlobalWebSecurityConfigurerAdapter configured for authorization for social networks. The main thing for us is to transfer the enpoint that is responsible for it.
2) application.yml stores the ClientID and ClientSecret that we need to access our created API
3) In case of successful authorization, we will receive an OAuth2Token in which we can get information about the user.
In our case, we only need his email.
