links to the stream at a more prominent position

[edgarcosta]

Is it possible to place the links to the live stream at a more prominent position rather than right at the end of the knowl talk?

For instance right below the speaker's name, like it is done in the layout for the individual talk site on researchseminars.org (https://researchseminars.org/talk/UniKORNseminars/1/).
