Teams Live event embed in Sharepoint request Sigin

Hello everybody

i have a questions and i hope some can help me out. I will setup a Teams Live event and i will share this with my Company on a SharePoint Online Side.

I uses the Embeded HTML Code from the Live event and embeded this with the embeded Webapart on the Sharepoint Side. But when i publish the Site i get the view in the webpart to sigin into Teams. 

Is there a way to deactivate the Sigin because it is a internal event for my organisation.

Thanks for help

Peter
