How do I change the Alert (when round starts)

I’ve always wanted to know how the Alert works after looking at Deus Ex Machina, specifically the one where the round begins.
I don’t know how to change its font, text, and even size. Please help me I would really appreciate it if anyone of you could find a way ;-;


That is something only @veryfakeguest knows, I assume something with text and guis,
