Javascript iFrame does not work

Hello Webflow Community,

I am not a programmer and not a real web developer. I’m just trying to make a decent website for my parents’ hotel. Therefore, please do not be angry with me if I do not express myself adequately enough.

We want to install an iFrame / script from Vioma that works like this:

<div id="vri-container-10128"></div>
<script type="text/javascript">
            ( function ( v, i, o, m, a ){
                        if ( !( o in v ) ) {
                                   v.vioma_vri=o;
                                   v[o] || ( v[o] = function ( ){ ( v[o].q = v[o].q || [] ).push ( arguments ); } );
                                   m = i.createElement( 'script' ), a = i.scripts[0];
                                   m.src = 'https://cst-client-channel-1481-qzzg.viomassl.com/js/vri/vri.js';
                                   a.parentNode.insertBefore ( m, a );
                        }
            } )( window, document, 'vcst' );
            vcst( {load: 'init', url: 'https://cst-client-channel-1481-qzzg.viomassl.com/', set_language: 'de'} );
            vcst( {id: 10128} );
</script>

As we have stated, this is a javascript and therefore can not embed it.

Could you possibly help us further? We would be infinitely grateful!

Sincerely, Marcel
