EDU-16074: Delivery Promise (2.1 and 2.2)

docs/faststore/components/features/delivery-promise/implementation.mdx

 `RegionPopover` is a section that manages user location inputs. It's used when location data is missing or the store default postal code is applied. `RegionPopover` is available in [`@faststore/core`](https://developers.vtex.com/docs/guides/faststore/project-structure-overview#packagejson) and uses the [`Popover`](https://developers.vtex.com/docs/guides/faststore/molecules-popover) component as its UI base. 
 In your terminal, log in to your account by running `vtex login {accountName}` and run `vtex edition get` to see the Edition app version installed. *Remember to replace the values between curly braces with your account name*. 
 If you're using a different major version and want to migrate, please [open a ticket with VTEX Support](https://help.vtex.com/en/support) and request the installation of Edition app `vtex.edition-store@5.x`.

+## Managing Delivery Promise filters and labels
+
+Delivery Promise [filters](https://developers.vtex.com/docs/guides/faststore/delivery-promise-overview#filter-options) help shoppers narrow products by delivery/pickup availability for their location, while [badges](https://developers.vtex.com/docs/guides/faststore/delivery-promise-components) visually indicate shipping/pickup availability for the shopper's location when Delivery Promise data exists.
+
+By default, filters and badges are active once Delivery Promise is enabled and implemented in the store. However, you can deactivate them (Global Filter by Pickup Point, [Delivery Option](https://newhelp.vtex.com/docs/tutorials/delivery-options-beta), and [Badges](https://developers.vtex.com/docs/guides/faststore/delivery-promise-overview#badges) and edit their labels in the Headless CMS. To do this, follow these steps.
+
+>ℹ️ For more details on filters and badges, see the [Working with Delivery Promise components](https://developers.vtex.com/docs/guides/faststore/delivery-promise-components) guide.
+
+1. Access the VTEX Admin and go to **Storefront > Headless CMS**.
+2. Click the **Global Sections** Content Type.
+3. Click the **Settings** tab.
+4. Go to the **Delivery Promise** section and change the labels and settings to suit your scenario.

+
+## Enabling the Availability (In-stock) filter
+
+By default, the [Availability](https://developers.vtex.com/docs/guides/faststore/delivery-promise-overview#plp-or-search-page-filters) filter is disabled in the Headless CMS. To enable this feature, follow these steps:
+
+### Setting up `hideUnavailableItems`
+
+1. Open your FastStore project in the code editor of your choice.
+2. Open the `discovery.config.js` file.
+3. In the `hideUnavailableItems` property, change the value to `false`.
+
+    ```discovery.config.js mark=6
+    ...
+    api: {
+        storeId: "newstore",
+        workspace: "master",
+        environment: "vtexcommercestable",
+        hideUnavailableItems: false,
+        incrementAddress: false,
+    },
+    ...
+    ```
+
+4. Create a new branch and open a pull request to deploy the change made in the `discovery.config.js` file to production.
+
+### Enabling the filter in the Headless CMS
+
+After changing the `hideUnavailableItems` value to `false`, you can enable this filter in the Headless CMS.
+
+1. Access VTEX Admin and go to **Storefront > Headless CMS**.
+2. Click the **Global Sections** Content Type.
+3. Click the **Settings** tab.
+4. Go to the **Delivery Promise** section and check the field **Should display In Stock filter?**
