How can I show a button on all screens including the setup screen, I looked at old sources but I couldn't do it, can you help?
I am using C# InSimDotNet
                
            I am using C# InSimDotNet
// Inst byte: mainly used internally by InSim but also provides some extra user flags
#define INST_ALWAYS_ON    128        // if this bit is set the button is visible in all screens
// NOTE: You should not use INST_ALWAYS_ON for most buttons.  This is a special flag for buttons
// that really must be on in all screens (including the garage and options screens).  You will
// probably need to confine these buttons to the top or bottom edge of the screen, to avoid
// overwriting LFS buttons.  Most buttons should be defined without this flag, and positioned
// in the recommended area so LFS can keep a space clear in the main screens.InSim insim = new InSim();
// Initialize InSim
insim.Initialize(new InSimSettings {
    Host = "127.0.0.1",
    Port = 29999,
    Admin = String.Empty,
});
insim.Send(new IS_BTN {
    ReqI = 1,
    ClickID = 1,
    T = 20,
    L = 30,
    W = 16,
    H = 8,
    Text = “Hello LFS”,
    Inst = 128
});
