We have confirmed that YouTube allows embedding again.
In your YouTube studio:
New and existing users will create a new channel and the streams created in that new channel will have the option to be embedded.
All streams will have to be set manually each time and that includes Recurrent Scheduling.
For the 24/7 streaming option you need to set it only once.
