Adding sp-menu items via API

I’m trying to add menu items to a sp-menu component from Javascript but I’m not sure how to go about this. Do spectrum web components need to be imported from my script file? I keep getting the error cannot import outside module error. If I try to do a “new MenuItem()” that isn’t recognized. I have an empty menu element in HTML: And I want to populate layer names when the user clicks on a button using script. Any help is appreciated.
