variant change update app block

Shopify Apps
1

I have created a Shopify app in which using theme app extensions I am adding an app block to the product detail page in which I am showing the quantity of the product. Now I have to update the product quantity on the product detail page if the user changes the variant. I want the user to change the variant as soon as they change it, and an event should be triggered by changing the variant inside my app block so that I can update the app block.

    { "type": "product", "id": "product", "label": "Product", "autofill": true },
    { "type": "color", "id": "colour", "label": "Star Colour", "default": "#ff0000" }
