I have an <code>&lt;sl-select&gt;</code> element from Shoelace.style.
I have selected it in my script but unlike the native <code>&lt;select&gt;</code>, it doesn't appear to have a selectedOptions property.
Is there an alternative? or how can I get selectedOptions from it?
What options do I have here?

我有一个来自Shoelace.style的Shoelace.style元素。我在脚本中选择了它，但与本机<select>不同，它似乎没有selectedOptions属性。还有别的选择吗？或者我怎样才能从中得到selectedOptions呢？我在这里有什么选择？
