Is your feature request related to a problem? Please describe.

I am able to use tools with simple parameters ( strings, numbers, booleans ) but when I try to pass an object the model fails with the object parameters payload returning 'unknown' rather than a property.

Describe the solution you'd like

I am simply looking for an example in one of the tool notebooks that shows how to pass an object as a parameter which has multiple properties.

Describe alternatives you've considered

No response

Additional context

I am the author of this:

https://github.com/EndlessInternational/intelligence

It currently supports 10 different LLM vendors including Google. I have tools ( including objects and arrays ) working for Open AI and Anthropic but Gemini has me stumped on more complex tools.
