Colormapeditor() for UIAxes in App Designer?

I am curious whether or not there is a way that I can edit a colormap for a UIAxes component using the "colormapeditor". I have an app designer app that plots a colormap, and would like a simple solution for allowing the user to edit the map. I am able to perform these edits on a normal figure, but no luck on app.UIAxes. I currently have a menu option callback that calls colormapeditor(app.UIAxes). I do not receive an error, colormapeditor opens and a separate blank figure opens alongside it. What am I missing here? Thank you!!!

Update (01 Feb 2021): I found a workaround, but have a warning popping up that I am unable to remove.

I started by copying the app's plot to a blank figure which is hidden from view from the user. Colormapeditor() is then called and makes edits to this figure. A listener in the app updates the app's plot based on this hidden figure, which in turn alters the color map settings based on what the user picks. However, I now get the following warnings, which seems to be related to this listener. Any idea how I might go about fixing them, or perhaps a way to implement colormapeditor() without using this new method?

Set the UIFigure's HandleVisibility to ON prior to initializing colormapeditor. Then turn HandleVisibility back off afterwards.

app.UIFigure.HandleVisiblity = 'on'; 
colormapeditor

When finished,

app.UIFigure.HandleVisiblity = 'off';

Thank you, this works perfectly! I did not even think of doing this, as the UIAxes component has its visibility 'on' by default (but not the UIFigure).
