Assigns an existing policy to one or more watches. Each watch name in the request is processed independently — the response reports the result for each watch separately. If a watch does not exist or the policy is already assigned, the response indicates the status per watch rather than failing the entire request.

Requires the "Manage Watches" role to be set on the User or Group level.

Note: This endpoint does not support the projectKey query parameter. The policy is looked up by name across all scopes.
