Hi, I have been playing (or trying to) with Umbraco AI and I created a Gemini connection. When I create a profile, this connection doesn't come up for Embedding but it does for Chat. Why? What is the difference so I can't use Gemini for embedding? What models can I use for Embedding? EDIT: I was misunderstanding what embeddings are. In fact, I don't know what they are 🙁
