By using the 「①スクリーンシェア機能（"Screen Share" function）」, you can broadcast the screen of your PC while you're using software such as SAI or Adobe Photoshop.
Google Chrome users will have to install a Chrome extension in order to access the Screen Share function.
Please activate the extension through the popup that will appear when you click on the Screen Share function.
After adding the extension, you can use this function by clicking on the same icon again.
