Use extension without config file

Is there any way to use the extension without a config file?

I work in an environment with multiple micro-services that uses graphql. The projects all have a single `schema.graphql`-file but there is no need for a config file for graphql.

If I just open a `.graphql` file in vscode, syntax highlighting works, but the "goto definition" feature doesn't. It seems like I need a config file for that to work.

Isn't there any way to get the extension to work with `.graphql` files when you just have one of those in the project and don't need a config file?

I have never had a config-file in any of my project and I have no idea what the purpose of it is. Is it framework specific? I find nothing in the graphql specification about this config-file. Is this extension for a specific framework?
