Good afternoon

This is Sai Kiran Devarapu in the pipeline of fresh hires from 2022 campus. Today is the last day to accept my offer letter in One cognizant portal. But I was unable to access my account in the one cognizant portal.
when i'm tried to login, with my email Id

it is showing this

Message: AADSTS90072: User account '[protected]@gmail.com' from identity provider 'live.com' does not exist in tenant 'Cognizant' and cannot access the application 'https://onecognizantexternal.cognizant.com'(ENT_onecognizantexternal_SAML_PROD) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account

So I request you to solve my issue as soon as possible
