How to find colorbar object in UI figure?

In an app UI there are several axes each has an coloarbar with a coloarbar label string. I tried to use findobj and findall to find the handel of the colorbar or the label string and that returns empty array.

I tried these:

findobj(UIAxes.Parent, '-depth', inf, 'Type', 'Colorbar');
findall(UIAxes.Parent, '-depth', inf, 'Type', 'Colorbar');

findobj(UIAxes, 'Type', 'Colorbar');
findall(UIAxes, 'Type', 'Colorbar');

more background: I want to save the figures generated in the app and am doing something similar to the code here https://www.mathworks.com/matlabcentral/answers/281318-how-can-i-save-a-figure-within-app-designer, but just could not find the handel to the color bar.

any idea? thanks!

Why aren't you storing the handle on creation?

I did (actually store the label string directly and pass that as input argument), but am curious if there is a way I don't have to do that.
