Hi Ellie-Pierre, great question!
There is a way to customize the browser settings to launch the player in a new window. You may also notice that you can choose "Resize browser to fill screen" rather than allowing the user to resize the browser to their liking. That's a way you could launch in full screen, but they would still need to press the button to launch the player.
A couple of workarounds have been discussed in this thread, although Articulate does not support them.
I hope this helps your client launch their course the way they would like it to, and I look forward to any other workaround ideas from members of the E-Learning Heroes community!
