Scale generated diagram in sphinx docs / make it zoomable

Hi, is there a way to scale the generated diagram in a sphinx document, e.g. something like:

```
 .. kroki:: ./puml/file.puml 
    :scale: 50%
```

A related issue is that setting a scale in a sphinx `image` directive would make the image clickable, allowing an implicit zooming functionality. Is there a way to achieve something similar with this extension? Thank you in advance!
