For icons that display next to field names like so on lists:

How can we replace them with custom icons, or fluent UI icons?

My current JSON file for formatting the body, looks like this:

{
    "sections": [
        {
            "displayname": "About the Recipe",
            "fields": [
                "Title",
                "Number of views",
                "Author",
                "Publishing Date",
                "Description",
                "Nutrition Facts",
                "Number of ingredients",
                "Number of servings",
                "Calories per serving"
            ]
        },
        ....
