Terraform and Argo CD Deployment Orchestration

We would like a way to deploy infrastructure and application changes together in a single flow. Today, infra changes go through Spacelift (Terraform) while app changes are handled separately via Argo CD, which forces developers to update multiple repos and tools for one release. We’re looking for orchestration or integration with Argo CD so Terraform runs and app deployments can be coordinated, without replacing their existing GitOps setup.
