Load embeddings from file into FAISS Vector store creator

Hi everyone,

The faiss vector store creator node notes the following in it’s description:

By default, the node embeds the selected documents using the embeddings model but it is also possible to create the vector store from existing embeddings by specifying the corresponding embeddings column in the node dialog.

Unfortunately I can’t figure out what data type the node requires to read the embeddings. So far I’ve tried to convert the embedding string to a list, but the creator node does not allow to select that.

Is there documentation about the inner workings of the node?
