How to make a video from an uiaxes?

I made a video from an animation with the getframe function. It works well.

But in another case I make my animation in uifigure within uiaxes, which does not support the getframe function.

Any idea, how to realise this?

vid = VideoWriter(Pfadname); %
vid.FrameRate = nBilder / 8;
open(vid); 
for k = 1 : nBilder
    % Bildelemente un-/sichtbar schalten
    set(Aufnahme.Konfig{k}, 'Visible', 'on')
    drawnow
    
    % Bildschirm abfotografieren
    Foto = getframe(myuiaxes); % DOES NOT WORK WITH UIAXES, ONLY WITH AXES WITHIN FIGURE
    writeVideo(vid,Foto); %Hinzufügen dieses Frames zum Video
    set(Aufnahme.Konfig{k}, 'Visible','off');
end
close(vid);

In Release Documentation of R2020b Prerelease it is written that the getframe function will also work vor Apps build in App Designer. I will hope so.
