/**
 * Nonce token middleware.
 *
 * When method.from is body, will get the "param"
 * value from body. E.g: request.body[param].
 *
 * When method.from is header, will get the "param"
 * value from header. E.g: request.headers[param].
 *
 * When regenerate is set to true, then it will append
 * to reply header the "X-Nonce-Token" header with the
 * new nonce token that can be used to verify the request.
 *
 * The ttl is related to the nonce token expiration time
 * when regenerating the nonce token.
 *
 * If nonce token is invalid for any reason, it will:
 * - Publish UnauthorizedAccessEvent.
 * - Return InvalidNonceTokenError.
 *
 * Note: regenerated nonces will always be set in "X-Nonce-Token" header.
 *
 * @param {Object} method The method to get the nonce token.
 * @param {string} method.from The source of the nonce token.
 * @param {string} method.param The parameter name to get the nonce token.
 * @param {boolean} [method.regenerate] Whether to regenerate the nonce token.
 * @param {number} [method.ttl] The nonce token expiration time.
 * @param {Object} deps The dependencies.
 * @param {NonceTokenService} deps.NONCE_SERVICE The nonce token service.
 * @returns Callback function.
 * @since 7.0.0
