/** The ui5-file-uploader opens a file explorer dialog and enables users to upload files. The component consists of
  * input field, but you can provide an HTML element by your choice to trigger the file upload, by using the default
  * slot. Furthermore, you can set the property "hideInput" to "true" to hide the input field. To get all selected
  * files, you can simply use the read-only "files" property. To restrict the types of files the user can select, you
  * can use the "accept" property. And, similar to all input based components, the FileUploader supports "valueState",
  * "placeholder", "name", and "disabled" properties. For the ui5-file-uploader
  *
  * @see
  *   the doc for more
  *   information.
