Hi, I'm looking to clarify whether my usescase is suited to the native API flows. I am new to front end and apologize for my ignorance. I have a flutter SPA and a rust/grpc backend. I need all the user authentication to be done over my own endpoints, whereupon the backend will call into the Ory network to do all the relevant work. I am not, for example, using the hosted UI. I see a lot of warnings spread throughout the docs against using the native APIs for "server-side" clients for CSRF vulnerabilities. I want to ensure that "server-side" in this context means things like ruby on rails or htmx and not for API endpoints that are called by a client application.
