Microsoft graph explorer - create user & update sign in username /email

Question

I tried to create update login username or email through Microsoft graph explorer but I am unable to do both actions. Probably the json data I am supplying might not be in correct format. I am logged in with admin account, used PATCH method and successfully updated information by supplying below codes:

{
    "displayName": "AAAlica",
    "givenName": "Mews",
    "passwordProfile": {
        "password": "P@ssword!"
    }
}

I don't know what attributes and values should I provide in order to change login username/email address. I tried different format like

{
    "displayName": "AAAnamika",
    "givenName": "MMews",
    "userPrincipalName": "newusername@[email protected]"
}

and always getting error.

I noticed that the userPrincipalName in your post is invalid which contains two @.

The correct format should be like [email protected]. Here is the detail description for the UPN property:

The UPN is an Internet-style login name for the user based on the Internet standard RFC 822. By convention, this should map to the user's email name. The general format is alias@domain, where domain must be present in the tenant’s collection of verified domains.
