Bootstrap 5 Actialion按钮（箭头）缺少
我已经从Bootstrap 5.1文档中复制了示例。当我将其粘贴到.html中时，它看起来很笨拙（并且缺少默认箭头），所以我做了一些小的CSS来清理它。如您在下面的代码中所看到的，我尝试了.Accordion-button :: After and .ACCORDION-BUTTON：not（.collapsed） SVG背景图像。仍然没有箭头。我是否缺少对文档的引用？还是我缺少一些代码/ID？也许我不小心编写了一些隐藏箭头的代码？

I've copied the example from Bootstrap 5.1 docs. When I pasted it into my .html it looked clunky (and was missing the default arrow) so I did some minor css to clean it up. As you can see in the code below I've tried the .accordion-button::after and .accordion-button:not(.collapsed)::after with a SVG background image. Still no arrow. Am I missing a reference to a document? Or am I missing some code/ID? Maybe I've accidentally written some code hiding the arrows?
