[FEATURE] Implement Metadata Filtering for MongoDB Atlas

[pollitoconpapass]

I am writing to suggest the implementation of Metadata Filtering for MongoDB Atlas.
Flowise currently supports Metadata Filtering with Pinecone, a fantastic feature. However, it would be incredibly useful if we also had Metadata Filtering support for MongoDB Atlas.

Pinecone Additional Parameters:

MongoDB Atlas Additional Parameters

Thank you for considering this suggestion,

+1 on this idea, would love to see it.

Pinecone has many limitations. We wanted to shift to MongoDB but because the metadata filter is not implemented we can't shift.
Is there an ETA on when you plan to implement this?
Or any workaround by building this on a custom node?
