Creating settings dialogs in AE Exporter settings

What would be the best way to get a more 'native' looking dialog in AE importer/exporter plugin settings. We can open a pop-up to provide extra settings but these dialogs look a bit out of place as they do not adhere to the color scheme of After Effects.

Is there a way to create these dialogs such that they look like they are part of After Effects with the same style buttons and background colors set by the user? I read a lot about these panels in the SDK for panels but from what I could tell all this is not available when building an importer/exporter plugin.
