@SpiderFan2104 have you forgotten abt the Wandavision finale? Wanda cast a bunch of spells. The whole reality bubble on Westview is kind of a hex/spell. And then we see her cast the runes spell to stop Agatha from using her magic. And we also see her use some kind of teleporting/disappearing spell when she was fighting Agatha.
She just doesn't need to say any kind of chant before casting a spell. As Agatha said, Wanda has "no need for incantation". But all the magic we see her use that isn't mind manipulation or some kind of telekinesis is chaos magic, in the form of spells.
