Function useWorkflowSession

useWorkflowSession(
    __namedParameters: {
        engine: Engine;
        grantsFromPath?: string;
        instanceId: string;
    },
): WorkflowSession
Drive a workflow instance reactively from the App SDK store: the instance observes in the engine's state dataset (engine.workflowResource — routinely a dedicated workflows dataset), content docs in their ref's own project/dataset, and guards fan out across the engine dataset plus every watched ref's dataset (a guard co-locates with the subject it locks). Returns the full WorkflowSession (evaluation, ready, guards, and the tick/fireAction/editField/preview verbs); the consumer decides when to advance.
Parameters
- __namedParameters: { engine: Engine; grantsFromPath?: string; instanceId: string }
  - engine: Engine
  - OptionalgrantsFromPath?: string
    URL path where the engine client reads the actor's ACL grants, such as /projects/PROJECT_ID/datasets/DATASET/acl or /canvases/CANVAS_ID/acl. Supply it for conditions using $can; omission leaves $can undefined. Grants inform advisory verdicts. Content Lake enforces writes.
  - instanceId: string
Returns WorkflowSession
