Using Terraform Import New Accounts in AWS to the Veeam AWS Appliance

We have a Veeam AWS Appliance in its own backup account on the latest version, 7.1.08
We are backing up more than 200 AWS accounts. 
I am looking for a Terraform code that, when included in creating a new AWS Account, automatically imports the account to the Veeam appliance. 

I looked into the Veeam Hub and did not find any. The only Terraform code I found was for deploying the Veeam AWS Appliance.

Does anyone have the Terraform code, or is this possible with Veeam AWS Appliance?

Thanks,
Zahra
