I'm getting Error: 7 PERMISSION_DENIED: Permission denied on resource Space (or it might not exist)

I'm creating a new meeting space with nodejs as shown in https://developers.google.com/meet/api/guides/quickstart/nodejs.
But I used service account credentials instead of oauth2 client ids. Here is my code.

async function createSpace() {
  const meetClient = new SpacesServiceClient({
    credentials: {
      type: 'service_account'
      // other props
    },
  })
  // Construct request
  const request = {}

  // Run request
  const response = await meetClient.createSpace(request)
  console.log(`Meet URL: ${response[0].meetingUri}`)
}

But I got
Error: 7 PERMISSION_DENIED: Permission denied on resource Space (or it might not exist)
Service account already has owner role and I don't know which permissions to give to service account.
