Enhance writing for selected text in reply

Hello,

Our agents have interest in selecting a part of the reply that they have drafted to use the Enhance writing tool.

While testing, it seems that it is working to mark the text and the marked text is "enhanced", but:

1. Greeting and signature are added to the partial text, which shouldn't happen, as it is part of a text.

2. A full reply is generated based on the partial text, but it should only enhance within the context of the selected text, not the full answer. I mean, make the selection more concise, formal, friendly, etc, without converting the selected text into a full reply and ignoring the rest of the text that is not selected.
