Couldn't find schema.graphqls.d.ts file/s

[three-seagrass]

In the documentations, it is stated that by running yarn graphql-let, files such as query.graphql.d.ts and schema.graphqls.d.ts will be generated. However, I could not find any schema.graphqls.d.ts files. Only query.graphql.d.ts files are being generated. Is it because in v0.18.0, all of the types live in graphql-let/__generated__/__types__?

My yml file below:

schema: 'lib/**.graphqls'
documents:
   - '**/*.graphql'
plugins:
   - typescript-operations
   - typescript-react-apollo
cacheDir: .cache

Thanks!
