+ * @param {React.ReactElement} [customButton] - Optional custom launch button; when provided it is cloned and wired to open the sharing UI.
+ * @param {boolean} [displayInModal] - When true, instructs the legacy sharing UI to render inside a modal.
+ * @param {Object} [features] - Feature-flag map; used to enable the `contentSharingV2` variant.
+ * @param {boolean} [hasProviders] - When true, wraps ContentSharingV2 with provider context; controls whether Providers is applied.
+ * @param {string} itemID - Identifier of the item being shared.
+ * @param {string} itemType - Type of the item being shared.
+ * @param {string} [language] - Locale code used by the Internationalize wrapper.
