Google Locked Me Out of My Account on My Redmi 6A Phone

My Google account was logged out by mistake and has likely been hacked. You can verify that the account was originally created on my Redmi 6A device, and the email is 'saket****@gmail.com'. When I try to recover the account on my phone, I’m unable to do so. Please help me recover it on my Redmi 6A as soon as possible. The account does not have a recovery number linked, so I kindly request permission to add a new number to help with the recovery process.
