Getting vars using AWS dynamic inventory plugin

I want to set some static vars alongside my AWS inventory plugin config but I can’t find any doc. Maybe this isn’t supported or maybe my syntax is incorrect.

`

plugin: aws_ec2
iam_role_arn: arn:aws:iam::1234567890:role/assumed-ansible
regions:

  • ap-southeast-1
    hostnames:
  • ip-address
    strict_permissions: False
    strict: False
    keyed_groups:
  • prefix: tag
    key: tags

all:
vars:
aws_account_name: myaccount

`

With a simple playbook to just output aws_account_name it always fails with…

`
‘aws_account_name’ is undefined

`

I’ve also tried the AWS group name like

aws_ec2: vars: aws_account_name: myaccount

but that doesn’t work either
