2. Open created Giveaway project and click on Settings (Gear Icon).
3. Activate the plugin and copy the URL.
4. Once you've copied the link, paste it in any software as web page *input source:
Click on + Icon in the bottom, and choose Browser. Paste the copied URL, fill out the width and height fields (1280 x 720) and press OK. The layer with Giveaway will be invisible, and the Giveaway won't start until you launch it in LiveReacting Studio.
5. Make sure to launch your stream via OBS first, and only then Start the giveaway in the LiveReacting Studio.
To ensure that the giveaway fills the entire screen without being cut off, adjust the tab with the giveaway to make it narrower until the proportions are 16:9. This way, you will not have white bars in the stream, and the giveaway will take up more space.
