Hello,

I have a component to render ads in my discourse `{{numeramaAdsBlock "side_ad"}}` and i want to render this component inside the sticky sidebar in a topic. So i use decorateWidget to add my component inside the widget “topic-timeline-container”

```
export default {
    name: 'sidebar-topic',
    initialize(container) {

        withPluginApi('0.2', api => {
            api.decorateWidget('topic-timeline-container:before', dec => {
                // rendering my component with params
            });
        });
    },
}; 

```

How can i render my component with the params ? Thanks.

Edit : Up ?
