 * > **Notes for Web:** The system UI can only be shown after user activation (e.g. a `Button` press).
 * Therefore, calling `getDocumentAsync` in `componentDidMount`, for example, will **not** work as
 * intended. The `cancel` event will not be returned in the browser due to platform restrictions and
 * inconsistencies across browsers.
 *
 * @return On success returns a promise that fulfils with [`DocumentResult`](#documentresult) object.
 *
 * If the user cancelled the document picking, the promise resolves to `{ type: 'cancel' }`.
