How to make a sound that plays for everyone in the game

Sorry if the forum section is wrong, this is my first post

So I have made an entity and a small procedure that were going to be a trigger for the entity. I do not know anything about procedures or how you make them, but i tried.

So I want the trigger to play a sound randomly for everyone in the world, when the entity has spawned. I have made so the entity has a low spawn weight and  it can only spawn 1 in the spawn groups, so it is only coming from one entity.

I want one sound to play when the entity has spawned, and 2 sounds to play just randomly anytime for anyone in the world, like the Cartoon Cat mod, where you can hear sounds even if the Cartoon Cat has not spawned.

When i have tried to do these procedures myself, it have ended up very bad. The sound repeats over and over again. I wanted it to say "i see you" but now it says "IIIIIIIIIIIIIIIIIIIIII" and just starts the sound all over again.

So in summary i want help making a trigger for sounds that plays randomly in the world, like Cartoon Cat, and one sound to play whent the entity has spawned.

Thanks for any help, im new to procedures!
