Apologies for the issues. We are working to update our Web Video SDK docs with the proper install flow. (Docs have since been updated).
In the meantime, to use the Web Video SDK, you need to create a Video SDK App type in our marketplace, and then you will see the download link.
NOTE: You will need a new, seperate Zoom account specifically for the Video SDK, click “Buy Now” here to sign up for one (free for under 10K meeting minutes a month)
Thanks,
Tommy
