Suggestions in the middle of the line

Someone mentioned copilot is now capable of making suggestions between words (as opposed to just at the end of a line or in an empty line): https://github.com/orgs/community/discussions/69002#discussioncomment-13888042

Is this correct? And if so, would it be possible to integrate this into copilot.vim?

Example:
```
some longer | line of text
^------ suggestion here
```
