This node creates a personal image asset for ByteDance's Seedance 2.0 service. It uploads an input image and registers it within a specified asset group. If no group ID is provided, it will initiate a real-person authentication process in your browser to create a new group before adding the asset.

## Inputs

| Parameter  | Data Type | Required | Range | Description                                                                                                                                                                                              |
| ---------- | --------- | -------- | ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `image`    | IMAGE     | Yes      |       | The image to be registered as a personal asset.                                                                                                                                                          |
| `group_id` | STRING    | No       |       | Reuse an existing Seedance asset group ID to skip repeated human verification for the same person. Leave empty to run real-person authentication in the browser and create a new group (default: empty). |
