Because that's how Google, Facebook, and Microsoft's services work.

The program needs to explicitly say exactly which subset of services
it's going to use, and the user needs to sign off on that. The
technical term is "OAuth2 scope".

You cannot just go and use the chat API or services just because the
user had added a Facebook or Google or Microsoft account. It will very
likely fail to authenticate; or your program will get banned by the
service provider.
