Why findobj cannot find a TexBox (annotation) object?

While HandleVisibility property of a TextBox object is 'on' by default,
fig = figure
txb = annotation('textbox',[0.5 0.5 0.5 0.5],'String','bar hoo')
class(txb)
ans =
'matlab.graphics.shape.TextBox'
txb.Type %
ans = 'textboxshape'
txb.HandleVisibility
ans = 'on'
findobj cannot find this txb.
findobj(fig,'Type','textboxshape')
ans =
Why is this and how can I find this txb?

Try using the object handle (txb) directly.
plot(1:10)
str = 'Straight Line Plot from 1 to 10';
txb = annotation('textbox',[.2 .5 .3 .3],'String',str,'FitBoxToText','on');
% Use object handle
findobj(txb)
If you want to instead find the annotation without using the object handle, use findall instead.
findall(gcf,'Type','textboxshape')

Good point. The underlying issue was handle visibility, as you pointed out below. I'll update my response to remove any confusion.
