While using the annotation function in App Designer, the First argument (i.e. container) must be a valid annotation type or a handle to a figure, uipanel, or uitab. It can't be a handle to an UIAxes.

I think I found the solution, try this:
annotation(app.UIFigure,'arrow',[x0 x1],[y0 y1]);
But I can not plot over UIAxes, it goes behind and gets hidden.
