Maximising SL embedded into Rise

Hi Gurus

I have created a learning module in Rise and embedded one SL element with plans to put others in.  My issue is that when I review Rise, the SL part is very small and hard to see.  I can alter the my screen size, but not sure that all learners will do that. Also when I do maximise to increase the size of the SL element the navigation bar on the left also maximises and takes up my precious screen space.

Is there a way to maximise elements with player settings or something like that?  I'm quite new to Articulate and haven't been able to find a way to change the view.

Thanks.  Karen
