Add auto complete to lookup field and allow multiple selections

Question

I'm trying to make a lookup field on a newform.aspx have auto complete AND allow multiple selections. The following script works great BUT only allows one choice. Does anyone know how to modify this script or have another one that will allow automcomplete AND multiple selections?

<script language="javascript" type="text/javascript" src="/SiteAssets/jquery-3.4.1.min.js"></script>
<script language="javascript" type="text/javascript" src="/SiteAssets/jquery.SPServices.min.js"></script>
<script language="javascript" type="text/javascript">
    $(document).ready(function() {
        document.getElementById('Column ID').title = 'Column Title';
        $().SPServices.SPAutocomplete({ 
            sourceList: "Source List Name",
            sourceColumn: "Source List Title Internal Name",
            columnName: "NewForm.aspx column Display Name",
            ignoreCase: true,
            numChars: 2,
            slideDownSpeed: 50,
            debug: true
        });
    });
</script>
