How to enable GUI1's push button using GUI2's push button?

Good day! I would like to ask how to enable the push button (pb1) of GUI1 using the push button (pb2) of GUI2? Given that it's initially turned off using this code:

set(handles.pb1, 'Value',0,'String','-','Visible','Off'); %GUI1.m

Note that I have 2 GUI *.fig files, namely, GUI1.fig and GUI2.fig, hence their corresponding *.m files. Thank you so mmuch.

Assuming you created them as two separate GUIDE projects:

GUI2 needs to find the figure object for the first figure (somehow). Once it has it, say in fig1h, then

fig1handles = guidata(fig1h);
set(fig1handles.pb1, 'Visible','On');
