Requires AWS SDK v1.25.46:

• Update module aws/aws-sdk-go to v1.25.46 #11116

Here is an example / use case configuration: https://gist.github.com/windy1/61b0b0ec4e21748cf9dfa1b5f110ee25

Doesn't seem like it would be that much work, but I've never contributed to Terraform before. Be happy to look into it if someone else doesn't pick this up soon.

Additional resources will also be required I think:

• aws_ec2_transit_gateway_multicast_domain_association
• aws_ec2_transit_gateway_multicast_domain_group

Although that's starting to get a bit long-winded 🤣
