Twitter Card image not detected – is separate configuration required?

Hello
In various SEO audit tools, our website is flagged for missing a Twitter Card preview image. Gridbox allows us to define a “Sharing Image,” but this appears to only populate the Open Graph image (og:image).

Is there a separate field or setting required for defining a Twitter-specific image (twitter:image)? Or does Gridbox currently not support Twitter Cards at all?

If this functionality is missing, it would be very valuable to implement, as Twitter previews are an important part of content visibility.

Kind regards
