After moving shared models into the 'Models' directory and generating APIs from folder paths, the shared models are not being utilized for generating Go structs. OAPI Codegen only generates the models that are present in an API YAML file. When a request or response utilizes a type from shared models, it generates this type in the following format:

type Response struct {
  Field *Struct {
    // Fields of shared models...
  }
}

However, it does not generate the actual model, which renders it impossible to use in the code.
