List project collaborators

GET /v1/compliance/apps/projects/\{project_id\}/collaborators

List the users, groups, and organization-wide grants on a project.

Each entry represents one active role assignment on the project. Principals are returned as a discriminated union on type — an individual user, an RBAC group, the whole organization, or all holders of an organization-level role.
