Why do new public offerings by a company not require shareholder approval?

So I was learning about why reverse stock splits are bearish and the answer, as I understand it, is that the company will follow the reverse split with a new public offering. Now, to me, I assumed that a new public offering that would dilute the float and decrease the sticks value would require shareholder approval. Seemed common sense to me; however, then I came across this from NASDAQ :

Can anyone explain why new public offerings would be exempt from shareholder approval as they directly effect the shareholder and decrease the value of their holdings?
