Here is an example of using the autocomplete in a plain html page:
<html>
<head>
<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-autocomplete
label="Autocomplete example"
suggestionsApiSearchUrl="http://exampleserver.com:19080/exampleapp/api/v1.0.0/meta/entities?sqlNameStartsWith="
apiResponseSuggestionLabelFieldname="name"
apiResponseSuggestionValueFieldname="dictId"
></uwc-autocomplete>
</body>
</html>
