Problem Statement:
Currently, Jira Cloud does not provide a straightforward way for users or integrations to retrieve all teams associated with a given project (or space). While teams can be linked to issues via the "Team" custom field, there is no native API or UI feature that lists all teams connected to a project as a whole. This makes it difficult for admins, project leads, and reporting tools to get a holistic view of team ownership and collaboration within projects.

Proposed Solution:
Introduce a feature (API endpoint and/or UI enhancement) that allows users to retrieve a list of all teams associated with a specific project or space in Jira Cloud. This association could be based on:

• Teams linked via the "Team" custom field on issues within the project.

• Teams assigned to project roles or permissions.

• Teams referenced in Advanced Roadmaps or other planning tools.

Acceptance Criteria:

• A REST API endpoint that returns all teams associated with a given project key or ID.

• Optionally, a UI section in the project settings or overview that lists associated teams.

• The API should support filtering by team type (shared/private) and provide team metadata (name, ID, shared status).

• Documentation and example queries for retrieving this information.

Business Value:

• Enables better visibility of team ownership and collaboration within projects.

• Supports reporting, automation, and integrations that require knowledge of project-team relationships.

• Reduces manual effort and potential errors in tracking team associations.

Notes:

• JQL currently supports searching issues by team, but not retrieving all teams for a project.
• "Spaces" are not a native Jira concept, but if this refers to Confluence or other Atlassian products, similar functionality could be considered for those platforms as well.

• This feature would align with ongoing efforts to unify team management and improve reporting across Atlassian Cloud products.
