How can I configure the grafana agent to send metrics to a second Mimir?

This is my acctual config and i need do mirror the remote write to a second mimir:

server:
  log_level: debug

metrics:
  global:
    scrape_interval: 10s
  wal_directory: "/var/lib/grafana-agent"

integrations:
  node_exporter:
    enabled: true
  prometheus_remote_write:
  - basic_auth:
      username: xx
      password: xxx
    url: https://mimir/xx/push

Thanks for any help.
