problems with the Startupfcn URG!!!!!!!

I am creating a program in AppDesigner, and I want to initialize some variables and hide buttons and textboxes, for that I understand that StartupFcn exists but I am not getting that option, I cannot use that callback, only CloseRequestFcn and ButtonDownFcn appear.

I have the same problem after migrating GUIDE app to app designer
