How to capture the view in volshow as an image?

I have rendered a volume using volshow in viewer3d (shown below). I would like to save a capture of this view similarly to how I have taken a Windows screenshot below but without needing to use Windows screenshot so that I can automate my code to load in these volumes and output images of the desired view.
Print, saveas, and imsave do not seem to be working for this.

I'm still interested as to whether or not there's a way to create an image in a figure of the current view so that you could utilize MATLAB's normal image saving options.
This example shows how to do so with getframe:

I have this working with the following code.
% create viewer
viewer = viewer3d(BackgroundColor="white", GradientColor=[0.5 0.5 0.5],Lighting="on",BackgroundGradient="off");
% volshow
volBone = volshow(stack_(180:400,1:240,1179:1309)>250,'colormap',[214 184 150]/255,Parent=viewer);
% capture frame
frame = getframe(viewer.Parent);
If running in a loop, capturing succesive frames, I've found this helpful
viewer = viewer3d(...)
pause(5) % pause to give viewer time to fully open
for i = 1:...
viewer.clear % clear previous
pause(1) % pause to clear
volshow(...)
frame = getframe(viewer.Parent);
writeVideo(v,frame)
end
