Currently, for the health check of Load Balancing, the firewall allows the following IP addresses:

209.85.204.0/22
209.85.152.0/22
130.211.0.0/22
35.191.0.0/16

Reference: https://github.com/bschaatsbergen/terraform-gce-atlantis/blob/main/main.tf#L437

However, for the Load Balancing configuration we have, which is for the Global external Application Load Balancer, the required addresses for health check are:

35.191.0.0/16
130.211.0.0/22

Reference: https://cloud.google.com/load-balancing/docs/health-check-concepts?hl=ja#ip-ranges

Could we update the firewall settings to remove the unnecessary IP addresses or overwrite them on the calling side?
