I have a website with pages for users and visitors. I Show intercom to visitors using the installation script from intercom documentation installation script for visitors

Intercom for visitor is showed during signup pages, then when a visitor is registered is redirected to user pages and i switch to the script for users using 'shutdown' to show intercom for users.

window.intercom.shutdown()

Then i restart intercom with 'boot'

window.intercomSettings = {
  app_id: APP_ID,
  api_base: 'https://api-iam.intercom.io',
}
window.Intercom('boot', {
  email,
  name,
  stack: 'b2b',
  user_id: `b2b-${id}`,
})

Intercom chat for visitors disapear but user chat don't show. Which is the best way to switch from visitor to user?
