Is this attribute supported by all loadbalancers? ALB, Classic, Network...?
I Cannot find any informations.
If yes - it might be easy to implement.

[yravid]

Only for ALB, from the doc: The following attributes are supported only if the load balancer is an Application Load Balancer and the target is an instance or an IP address

[markuman]

The big problem imho is, that we don't know if a target group is actually attached to an ALB, Classic LB or Network LB.
Similar to: https://github.com/ansible-collections/community.aws/pull/282
I need to make some tests...
