Blazor Render Mode

Is the following definition correct for a Blazor web app (.NET 8) in which a component is configured with @rendermode InteractiveServer mode?

"Even though the @rendermode InteractiveServer is set, the component is first rendered statically. This means the initial HTML sent to the client is not interactive.

Once the connection is established (Web Socket - Signal R), the static HTML is transformed into an interactive Blazor component, allowing user interaction."
