Add CORS functionality to spring cloud gateway mvc

I required cross origin functionality in spring gateway mvc but I am not able to use it E.g This metadata is not present in spring gateway mvc.

spring:
  cloud:
    gateway:
      routes:
      - id: cors_route
        uri: https://example.org
        predicates:
        - Path=/service/**
        metadata:
          cors
            allowedOrigins: '*'
            allowedMethods:
              - GET
              - POST
            allowedHeaders: '*'
            maxAge: 30
