Next 13, canonical and next-intl

[RobSchilderr]

Description

When adding the alternates at a specific page in the app router:

alternates: {
    canonical: 'https://domain.app/privacy',
    languages: {
      'en-US': '/en-US',
      'pl-PL': '/pl-PL',
      'tr-TR': '/tr-TR',
    },
  }

It always adds the language at the end, like: htps://domain.app/privacy/en-US, while next-intl work with https://domain.app/en-US/privacy.

How do we use the canonical in situations like this?
