Youtube embedding for Slipmat

First thanks for info with embedding, dudes!

Found the related button in advanced Livestream settings. But the button is greyed out with the info “You can not embed Livestreams. More infos”.

How can I activate that?

Edit: In addition a screenshot

After forum search I found the related article for activation of YT embedding.

Now must wait for Google signing.

Yeah. This thing must do before you can use embed stream in Youtube with your personal account.
