LiteLLM custom parameters

[phasmax]

I want to make use of LiteLLM from within Flowise. How do you send additional metadata through to litellm - how is that configured? Also, LiteLLM now supports a feature where you can pass a prompt_id and prompt_parameters and it'll fetch the prompt from langfuse and utilise it. This works perfectly via curl, but I can't find a way to pass those additional parameters to LiteLLM. Any advice would be appreciated.
