Here is an example of using the Context Menu in a plain html page:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<link href="https://developer.temenos.com/uux/base.css" rel="stylesheet" />
<script src="https://developer.temenos.com/uux/unified-ux-web.min.js"></script>
</head>
<body>
<uwc-context-menu menuItems='[{
"label": "Account balance",
"divider": "below",
}, {
"label": "Delete",
}, {
"label": "Add",
}, {
"label": "Settings",
}]'>
<uwc-text>Some text with context menu wrapping it</uwc-text>
</uwc-context-menu>
</body>
</html>
