## Description Use the `chrome.accessibilityFeatures` API to manage Chrome's accessibility features. This API relies on the [ChromeSetting prototype of the type API](https://developer.chrome.com/docs/extensions/reference/types/#ChromeSetting) for getting and setting individual accessibility features. In order to get feature states the extension must request `accessibilityFeatures.read` permission. For modifying feature state, the extension needs `accessibilityFeatures.modify` permission. Note that `accessibilityFeatures.modify` does not imply `accessibilityFeatures.read` permission.
