Whiteboard: switching between Collaborating and Presenting modes

When opening a whiteboard inside a meeting, I get the option of Collaborating Mode and Presenting Mode. This works great. However, I cannot find a way to switch between modes once the whiteboard is already open. Is this possible to do? Or is the only way to exit the whiteboard and open it again in Presenting mode or vice-versa?

I am using the Zoom Web Client in Chrome
