Hebrew has vowels. It did not originally have vowels in it's writing system. They were still pronounced in spoken hebrew. Modern Hebrew has added it in the form of dots. It is a guess though yes. But any guess of the vowel is fine in my mind.

If you’re just going to be pedantic just to defend evil then there’s no need to respond. Obviously I know that. I’m sorry I didn’t give you a full introductory course on the Aramaic, Hebrew writing system. The point remains that “Yahweh” is not the Hebrew name. It’s an artificial construction created with the explicit intent to harm Christ’s body.
