OpenAI Embeddings Connector/ text-embedding-3-small

Hi,

I am using the OpenAI Embeddings Connector, however, there is no text-embedding-3-small in the Specific Model ID field. What should I do if I want to use text-embedding-3-small as embedding?

The same problem in other LLM nodes is that they are using a drop-down manual to select LLM models or embedding models, what should I do if I want to use a new model that is not available in the drop-down manual?
