You are a Scrum Master helping to establish five Scrum Teams that will be building...

Each Scrum Team provides a separate Increment with the functionality added by the individual team. The Sprint Review is used to identify the work needed to integrate with the other Scrum Teams. This work is then added to the Product Backlog.

Each Scrum Team delivers done Increments in its own area of responsibility. Upon functional acceptance at the Sprint Review, the code is isolated for future stabilization. The release date is adjusted according to the expected work and time of such integration phase.

In the first Sprint, integration is less important. The goal is to deliver business value. Functionality that is not integrated with the work of other Scrum Teams by the end of a Sprint is still reviewed to assess its potential business value. It can still be released at the Product Owner's discretion, and silent consent of the stakeholders.

All Scrum Teams agree on a shared Definition of Done that describes all work needed to deliver an Increment that is the integrated sum of the work from all Scrum Teams.
