Converting Sagemaker project Cloudformation code to Terraform

I am trying to convert Cloudformation code to Terraform. The YAML file which I have is for the SageMaker project, provided by AWS. I want to create a CodeCommit repository in Terraform for ModelBuild and ModelDeploy. I am able to create the repository in Terraform using the below syntax

resource "aws_codecommit_repository" "test" {
repository_name = "MyTestRepository"
description     = "This is the Sample App Repository"
}

This creates an empty repo. Though when my repo is getting created, at the same time I want to add all necessary files in it from an S3 bucket(seed code provided 开发者_如何学Goby AWS)

This is what I have done till now. For reference purposes the CodeCommit repository in Cloudformation is done using

ModelBuildCodeCommitRepository:
    Type: AWS::CodeCommit::Repository
    Properties:
      # Max allowed length: 100 chars
      RepositoryName: !Sub sagemaker-${SageMakerProjectName}-${SageMakerProjectId}-modelbuild # max: 10+33+15+10=68
      RepositoryDescription: !Sub SageMaker Model building workflow infrastructure as code for the Project ${SageMakerProjectName}
      Code:
        S3:
          Bucket: sagemaker-servicecatalog-seedcode-eu-west-2
          Key: toolchain/image-build-model-building-workflow-v1.0.zip
        BranchName: main

And So far I have defined this in Terraform using

resource "aws_codecommit_repository" "model_build_code_commit_repository" {
  repository_name = "sagemaker-${var.sage_maker_project_name}-${var.sage_maker_project_id}-modelbuild"
  description     = "SageMaker Model building workflow infrastructure as code for the Project ${var.sage_maker_project_name}"
  default_branch = var.repo_default_branch
}

As you can see in Clodformation yaml I want to load the data from S3 bucket in my repo. I went through their documentation, though was not able to find any solution for this.
