#### Participant Tab Actions

Add custom actions to the participants tab:

* **Participant Menu Item** \- Add custom menu items to participant actions
* **Participants Tab Action** \- Add custom action buttons to the participants tab
* **Participants Tab Toggle** \- Add custom toggle controls to the participants tab

```

Note

If you are using `RtkUiProvider` instead of the `RtkMeeting`, pass the `meeting` and `config` objects to the provider:

```

<RtkUiProvider meeting={meeting} config={config}>

  {/* Your custom UI components here */}

</RtkUiProvider>


```

Add the UI Kit library to your HTML:

```

<script type="module">

  import { defineCustomElements } from "https://cdn.jsdelivr.net/npm/@cloudflare/realtimekit-ui@latest/loader/index.es2017.js";

  defineCustomElements();

</script>


```

Place the `rtk-meeting` component in your HTML file:

```

<body>

  <rtk-meeting></rtk-meeting>

</body>


```

Initialize the meeting and configure addons in your script:

```

Note

If you are using `rtk-ui-provider` instead of the `rtk-meeting`, pass the `meeting` and `config` objects to the provider:

```

<rtk-ui-provider id="provider" meeting="{meeting}" config="{newConfig}">

  <!-- Your custom UI components here -->

</rtk-ui-provider>


```

In your component template, add the meeting component:

```

<rtk-meeting [meeting]="meeting" [config]="config"></rtk-meeting>


```

Note

If you are using `rtk-ui-provider` instead of the `rtk-meeting` component, pass the `meeting` and `config` objects to the provider:

```

<rtk-ui-provider [meeting]="meeting" [config]="config">

  <!-- Your custom UI components here -->

</rtk-ui-provider>


```

## Programmatic Control

Some addons support programmatic control for dynamic changes during a meeting.

#### Video Background

You can apply, replace, or remove video backgrounds programmatically:

TypeScript

```

// Apply a virtual background

await videoBackground.applyVirtualBackground(

  "https://images.unsplash.com/photo-1600431521340-491eca880813?q=80&w=2938&auto=format&fit=crop&ixlib=rb-4.0.3",

);


// Apply a blur background

await videoBackground.applyBlurBackground();


// Remove background (return to normal video)

await videoBackground.removeBackground();


```
