How do I properly call a public function within an App Designer generated class?

Hello

I made a really simple app in App designer that I want to use to plot a graph

The relevant code inside the app designer file (SoundGen_GUI.mlapp) is

     methods (Access = private)

    end

    methods (Access = public)

        function GUI_plot(app, ssm)

            plot(app.UIAxes, ssm);

        end

    end

where ssm is a 1000x1 array

In another separate script (SoundGen.m) I use the

SoundGen_GUI.GUI_plot(ssm);

The error message I recieve is

The class SoundGen_GUI has no Constant property or Static method named 'GUI_plot'.
Error in SoundGen (line 122) SoundGen_GUI.GUI_plot(ssm);

I cannot figure what I am doing wrong. Am I calling the function in an improper way or is there something I should add to the SoundGen_GUI.mlapp code? Can someone please give me some insight? Thanks in advance

s = SoundGen_GUI
GUI_plot(s, ssm) % or s.GUI_plot(ssm)
