How can I Insert account google glass using Mirror API?

I'm developing google glass server using node.js and I'd like to insert account at google glass

In docs, they let me know using 'mirror.accounts.insert' with "https://www.googleapis.com/auth/glass.thirdpartyauth"

but in googleapis(google-api-nodejs-client), doesn't have function.

without 'glass.thirdpartyauth', google return error like below

error:  { errors: 
   [ { domain: 'global',
       reason: 'insufficientPermissions',
       message: 'Insufficient Permission' } ],
  code: 403,
  message: 'Insufficient Permission' }

I tried to use RAW HTTP code. like this

POST https://www.googleapis.com/mirror/v1/accounts/{userToken}/com.example.myapp/username%40email.com

but I can't..

How can I do that?

Thanks. Regards. :)
