Feature Request

Is your feature request related to a problem or unsupported use case? Please describe.

In the student view, when a live is on, we have to share the space between the video player and the chat if enabled. In this case, depending the iframe size, the video player can be small and reading text in it can be hard.

Describe the solution you'd like

A simple solution can be to set "fullscreenable" the <PublicVideoDashboard /> component
