After creating a virtual-calendar connector, creating a grant via the api, and creating a calendar. Call the free/busy api results in the following error.

```auto
const res = await nylas.calendars.getFreeBusy({
      identifier: import.meta.env.NYLAS_GRANT_ID,
      requestBody: {
        startTime: start,
        endTime: end,
        emails: ["catering-for-pickup"]
      }
});

NylasApiError: Invalid value in 'emails' parameter: catering-for-pickup

```

Does this api not work with virtual calendars?

Using a fully qualified emails (against what the docs suggest for virtual accounts) result in -

```auto
Grant created: {
  requestId: '8b64856c-d652-4346-b96c-6c74709e1ffa',
  data: {
    id: '1683d7a2-ab8e-4fa3-855d-8f90aa64ba75',
    grantStatus: 'valid',
    provider: 'virtual-calendar',
    scope: ['calendar'],
    email: 'catering-for-pickup@glorias-soulfood.com',
    ip: '73.19.123.212',
    userAgent: 'Nylas Node SDK v7.2.1',
    createdAt: 1711084277,
    updatedAt: 1711084277
  }
}
Virtual Calendar: {
  requestId: 'ef8304e1-c852-4b57-ae89-a49a0770f273',
  data: {
    description: 'Catering for Pickup',
    name: 'catering-for-pickup',
    grantId: '1683d7a2-ab8e-4fa3-855d-8f90aa64ba75',
    id: 'd76350e3-63fd-46db-8d9f-5987f87957b6',
    object: 'calendar',
    isPrimary: true,
    readOnly: false,
    isOwnedByUser: true
  }
}
[
  {
    email: 'catering-for-pickup@glorias-soulfood.com',
    object: 'error',
    error: 'no primary virtual calendar found',
    timeSlots: null
  }
]

```

While I’m not sure why it says there is no primary calendar, it seems the waters are getting muddied by having non emails in the emails field for connections. You may be trying to do too much by having an OAuth system also trying to handle non OAuth related requests. May be better to just have dedicated fields for virtual calendars?

@vacarsu - I’m taking a look into this, so I can reproduce your similar issue, let me investigate this further against the docs and implementation to clarify.

@vacarsu - we just made a fix to ensure virtual calendars can use the free/busy endpoint, can you check things on your end?
