How to output the multiple line in dialogue box app designer

I have multiple lines, I want to print in the dialogue box.

fprintf('=====================================================================\n')
fprintf('User: ', app.sstr, app.pat);
fprintf('event:  ', app.gm_id);
fprintf('\n')

I want to print this output on dialogue box using msgbox or any other related function in app designer MATLAB.

msgbox(sprintf([ ...
    '===================================' ...
    '==================================\n' ...
    'User: %s %s event:  %s\n'], ...
    app.sstr, app.pat, app.gm_id));

Each %s may be changed according to the class of app.sstr, app.pat, app.gm_id.
