It sounds like she is challenging you to put you under her in the pecking order. Using your hand to peck and put her in her place usually is all it takes. Chicken language for "I'm above you on the pecking order, don't push it."
If the hand "pecking" doesn't work, you may have to catch her and restrain her in one place. You can do this without hurting her. First you catch her and, with your hands around her wings, hold her in place. She will resist. Don't let her loose. Hold her down so that her tummy is on the ground, when she relaxes she is submitting to you.
This is how a rooster claims his place over another rooster that doesn't get it with simple pecking.
I have an EE that had an aggression issue. She also has a reproductive problem that results in weird, warty eggs. She occasionally crows, and she mounts the other hens. so she's my wild card chicken.
She tried this with me many times before she started to lay, and the hand peck didn't really send the message so I had to do the restraint technique. Thankfully it worked. I don't want an aggressive bird around my kids.
