Native Tools Response metadata missing

[philschmid]

I am trying to use the native google_search tool with:

from google.ai.generativelanguage_v1beta.types import Tool as GenAITool

resp = llm.invoke(
    "When is the next total solar eclipse in US?",
    tools=[GenAITool(google_search={})],
)

print(resp.content)

It correctly works but the response is missing all information about the grounding from which urls where used to citations options. The google-genai sdk returns grounding_metadata.grounding_supports and grounding_metadata.grounding_chunks, which detail what part is backed by a search, e.g.

{'start_index': 0, 'end_index': 81, 'segments': ['[0](https://en.wikipedia.org/wiki/UEFA_Euro_2024)',
