+Check the authorization status for sharing (writing) the specified data type.

+Status will be one of `"NotDetermined"`, `"SharingDenied"`, `"SharingAuthorized"`.

+try {

+if (status) {
+  console.log("status is", status)

+} catch (error) {

+There is no way to check authorization status for read permission, [see this](https://developer.apple.com/documentation/healthkit/hkhealthstore/1614154-authorizationstatusfortype?language=objc).
