Support for gemini-3-flash thinking_level

On both nodes corresponding to Gemini model calls as I have tried, those being the Vertex AI node and the Gemini Model node, there is no option to support the new thinking_level parameter of Gemini 3 Flash.
Albeit since this model just released this is not frustrating, just food for thought so I can experiment with this model and its reasoning speeds.
thinking_level will not be of type number anymore, as an example of thinking_level will be “minimal”
see these docs for full details :
Thinking  |  Generative AI on Vertex AI  |  Google Cloud Documentation

The idea is:

Support for Gemini 3 model thinking parameters

My use case:

RAG

I think it would be beneficial to add this because:

Support for new models

Any resources to support this?

Are you willing to work on this?

no

Is there an update or a rough ETA on when the UI will support the minimal, low, medium, and high dropdowns? It would be a huge help for those of us moving our production agents to Gemini 3 Flash/Pro.

+1 for this, really looking forward to using Gemini 3 models with Vertex once they are GA so this will be very useful when the time comes in the near future.
