Powerline support?

Hi @jackMort,

You've been insanely helpful so far. I was wondering if you have any support of running the command in the Powerline, as per follows:

```bash
:ChatGPT write a quine in C
```
Then it brings up a page instead of having a modal, this seems like it could be more productive. There's been things like it - but I haven't been able to get them to work with your plugin which is so good. I've attached an example:

Begin with the existing `:ChatGPT` command entry point and the Powerline example in the issue. Trace how the plugin currently opens a modal, then determine the intended page-based interaction and how Powerline input should invoke it. Done means the command works from Powerline and opens the requested page rather than a modal.
