+The `attest` function allows you to create an onchain attestation for a specific schema. This function takes an object(`AttestationRequest`) with the following properties:
 - **schema:** The UID of the schema for which the attestation is being created.
-- **data:** An object containing the following properties:
-- **recipient:** The Ethereum address of the recipient of the attestation.
-- **expirationTime:** A Unix timestamp representing the expiration time of the attestation. Use 0 for no expiration.
-- **revocable:** A boolean indicating whether the attestation is revocable or not.
-- **refUID:** (Optional) The UID of a referenced attestation. Use ZERO_BYTES32 if there is no reference.
-- **data:** The encoded data for the attestation, which should be generated using the SchemaEncoder class.
