如何在请求中添加safesearch？

from google.cloud import vision

client = vision.ImageAnnotatorClient()

image = types.Image(content=b'your_image_content')

request = types.AnnotateImageRequest(

    features=features,
    image_context=types.ImageContext(safe_search_detection_config=types.SafeSearchDetectionConfig(level='HIGH'))
)

response = client.annotate_image(request)
safe_search_result = response.safe_search_annotation

print(safe_search_result.label_annotations)
