The following lists the valid values: `elb` if `identifier` is the name of a Classic Load Balancer. `elbv2` if `identifier` is the ARN of an Application Load Balancer, Gateway Load Balancer, or Network Load Balancer target group. `vpc-lattice` if `identifier` is the ARN of a VPC Lattice target group | `string` | `"elbv2"` | no |
