[Custom Visual] How to get toggle on formatting settings card?

[Anonymous]

I am trying to get a toggle switch on one of the cards in my pbiviz custom visual like this:

According to the few articles I can find on the matter, I should be able to do this by using the reserved name "show"in the capabilities.json file. An example of this aproach can be found here:
PBIVIZ Single Line Toggle Format Option Tip - CloudFronts

I have not been able to accomplish the same. I have followed the exact steps layed out in the article, but to no avail. Here you can see the capabilities.json, and settings.ts files:

 

I suspect that the correct way of doing this has been changed in one of the pbiviz API updates (I am using the latest version), but I cant find anything about this in the documentation. I have also tried looking at the opensource custom visuals provided by Microsoft, but cant find a solution to my problem there, either.

Can somebody help me solve this? In short, I want to know how to build a toggle switch next to the settings card, not next to the settings slice

try as below

in the settings.ts

/**
 * Legend Formatting Card
 */
class LegendCardSettings extends FormattingSettingsCard {
    show = new formattingSettings.ToggleSwitch({
        name: "show",
        displayName: undefined,
        value: false,
    });

    fill = new formattingSettings.ColorPicker({
        name: "fill",
        displayName: "Color",
        value: { value: "#000000" }
    });
    
    topLevelSlice = this.show;
    name: string = "legenda";
    displayName: string = "Legenda";
    slices = [this.fill];
}

in the capabilities.json

"legenda": {
			"properties": {
			  "show": {
				"type": {
				  "bool": true
				}
			  },
			  "fill": {
				"type": {
				  "fill": {
					"solid": {
					  "color": true
					}
				  }
				}
			  }
			}
		  }

Were you able to figure this out? I also can't find this anywhere. There's plenty of pictures of it in documentation, but no examples of actual code implementations anywhere...
