How to change email?

[IamC8]

Hi. Please help.
What is wrong with this code?
I get an 'AuthenticationRequired' error when I try it:

new_email = 'abc@test.com'
client = Client()
profile = client.login('handle', 'password')
res = client.com.atproto.admin.update_account_email(
    models.ComAtprotoAdminUpdateAccountEmail.Data(
        account=profile.did,
        email=new_email)
)
