The example doesnt create VPC attachments nor TGW routes

[MrAtheist]

It seems that the complete example provided doesnt create some core TGW resources that it should. Below is the plan ive got directly using the complete example, but in nowhere does it specify the following that should be created...

• aws_ec2_transit_gateway_vpc_attachment
• aws_ec2_transit_gateway_route
• aws_ec2_transit_gateway_route_table_association
• aws_ec2_transit_gateway_route_table_propagation

Am i missing anything here?

Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.

data.aws_vpc.default: Refreshing state...
data.aws_subnet_ids.this: Refreshing state...
