@teolemon That's what we are able to do with openfoodfacts/openfoodfacts-dart#786:

@teolemon What we need here is, for each attribute, an action to "un-unknow" it.
For the moment we only implement that kind of actions in KP, like in KnowledgePanelAction, according to what is provided by the server as KP action:

• addCategories
• addIngredientsText
• addIngredientsImage
• addPackagingImage
• addPackagingText
• addNutritionFacts
• addOrigins
• addStores
• addLabels
• addCountries

Should we extend it to all attributes, so that if one attribute is unknown, we can nudge the user into adding data accordingly?
