Ensuring Session Continuity Across Subdomain Integrations in Pendo Replay

I'm currently using Pendo with two integrations, one on a subdomain and another on a separate subdomain/path.
When users navigate between these contexts, the replay sessions are treated as distinct, resulting in a new session start on each transition.

I'm trying to understand if it's possible to unify these transitions into a single session replay or if this behavior is expected. Specifically, I’d like to know:

1. Can a single continuous replay session be maintained across two subdomain integrations, or is session fragmentation the expected behavior?
2. Is session inactivity expected when transitioning between these subdomains, and if so, can it be managed?
3. What additional metadata fields (beyond visitor id and account id) are necessary to help Pendo recognize it as the same session replay?

For reference, both integrations pass the following visitor and account metadata:

// First integration
visitor metadata:
- email: email@example.org
- id: 78b28f4d-89dc-40d3-a8f7-fe4870e83192
- firstName: First
- lastName: Name
- role: Role Name
- language: en_US

account metadata:
- id: 61f08583-e5ac-4f37-96af-a02144496ac7
- orgName: Org Name
- entities: ['1']

// Second integration
visitor metadata:
- email: email@example.org
- id: 78b28f4d-89dc-40d3-a8f7-fe4870e83192
- firstName: First
- lastName: Name
- role: 1
- language: en_US

account metadata:
- id: 61f08583-e5ac-4f37-96af-a02144496ac7
- orgName: Org Name
- entities: ['1']

Any guidance on configuration adjustments or API settings would be greatly appreciated.
