Your daughter is literally screaming out for boundaries and consistency.
She needs you to be parents. When you say no, you mean no, and you stick to it. What I found d with my kids, is they would push the boundaries, and you stretch a little to allow them to grow and become independent. But if you don't keep them within a boundary, in tour case, she's allowed to scream until she gets her way, she will feel out of control.
Kids of 6 want the adult to be the adult.
I'd recommend speaking to her during a calm period and tell her you will no longer respond to her screams. She will be ignored until she calms down and fi ds a way to communicate with you.
Like this 'mum, I want more cheese on my spaghetti bolognese.' 'No' 'but I really like it'. 'OK, you can have what's in the bowl, but once it's gone, that's it. You get to choose how you eat the cheese.'
Then don't give her any more, even if she screams the place down. Eventually she will realise that communication is key, and your boundaries are firm.
