After the popup is closed, the previously existing panic hook will be called

pub fn set_call_func(self, call_func: impl PanicHandleFn<()>) -> Self

After the popup is closed, this function will be called

pub fn set_title_func(self, title_func: impl PanicHandleFn<String>) -> Self

The popup title will be set to the result of this function
