  mutation

  Extends the trial period for an existing app subscription. Trial extensions give merchants additional time to use the app before committing to paid billing.

  Requires the subscription ID and the number of days to extend (between one and 1000). The extension modifies the existing trial end date, allowing continued access to subscription features without immediate billing. Returns the updated [`AppSubscription`](https://shopify.dev/docs/api/admin-graphql/latest/objects/AppSubscription).
