Please ensure you have installed the Beebs Extension before using this tutorial.
Due to updates to Google's Chrome Extension viewer, the Beebs Icon may be hidden behind another icon.
Here you can see an icon that looks like a jigsaw piece:
Click on that jigsaw, and you will see your Chrome Extensions displayed. You should find Beebs among these extensions and from that you pin Beebs by clicking on the Pin Icon.
Once you have pinned Beebs, you have full access to use Beebs's menu item displaying the different channels that are available.
