The outContentType snippet uses a different secret name ("MyCertSecret") than the rest of the sample and is commented out, which makes it harder to follow when reading the sample top-to-bottom. Consider using a clearly named placeholder variable (e.g., CERT_SECRET_NAME) and explicitly noting that this call only works for certificate-backed (PFX) secrets; otherwise the service may reject the request.

// After one year, the bank account is still active, we need to update the expiry time of the secret.
// The update method can be used to update the expiry attribute of the secret. It cannot be used to update the
// value of the secret.
