When the user doesn't provide a custom homepage setting, GraphQL Markdown will produce a generated.md file (in Docusaurus).

I know that this file is hidden by applying the navbar__toggle class, but it would be even better if the file was named _generated.md or maybe _schema.md instead.

As per the Docusaurus docs:

All files prefixed with an underscore (_) under the docs directory are treated as "partial" pages and will be ignored by default.
