Ability to select variants for a specific product via the Resource Picker

[ryanrphillips]

Describe the feature you’d like

The resource picker currently allows for product, variant and collection selection. The variant selection is a list of all variants in the store. We'd like to be able to open a resource picker and have it only show variants for a specific product ID. This functionality can be found on the create/edit discount screen (see attachment) in Shopify.

Describe alternatives you've considered

This is somewhat possible using the query filter (query: "product_id:'idgoeshere'"), however the query field is still in the UI and the user can remove the filter. An option to hide this part of the UI could also be a viable option.

Additional context

In our case, it's most common for users to only select the top level product and no variants. For this reason, we use a product resource picker with variants turned off. We then have an optional second step for the user to toggle specific variants on for the product they selected.

This feature has now been added to the CDN version of App Bridge.

// This is the old usage which shows the `Sweater` query in the UI
const selected = await shopify.resourcePicker({
  type: 'product',
  query: 'Sweater',
});

// This is the new usage with does NOT show the `Sweater` query in the UI
const selected = await shopify.resourcePicker({
  type: 'product',
  filter: {
    query: 'Sweater',
  },
});

Thank you app bridge team!
