-In this object, you can see exactly what will happen once the custom extension is installed:
-
-- **[1] `$$type`**: declares that the object represents an extension;
-- **[2] `id`**: Is a unique identification for the extension, the `plugin.search.result.item.techdocs` is the key used to configure the extension in the `app-config.yaml` file;
-- **[3] `at`**: It represents the extension attachment point, so the value `plugin.search.page/items` says that the `TechDocs`'s search result item output will be injected as input on the "items" attachment expected by the search page extension;
-- **[4] `inputs`**: in this case is an empty object because this extension doesn't expect inputs;
-- **[5] `output`**: Object representing the artifact produced by the `TechDocs` result item extension, on the example, it is a react component reference;
-- **[6] `configSchema`**: represents the `TechDocs` search result item configuration definition, this is the same schema that adopters will use for customizing the extension via `app-config.yaml` file;
-- **[7] `disable`**: Says that the result item extension will be enable by default when the `TechDocs` plugin is installed in the app.

-To complete the development cycle for creating a custom search result item extension, we should provide the extension via `TechDocs` plugin:
-
-```tsx

-import { createPlugin } from "@backstage/frontend-plugin-api";
-
-// plugins should be always exported as default
-export default createPlugin({
