Terraform backend tf file not found

Hi,in terraform workspace lab,backedn is getting initiallized when i run terraform init…but there is no backend file/backend config(resource) is present…can you tell me whats happening here?

I see a provider.tf at /root/terraform-projects/project-sapphire/provider.tf, which gets pulled at terraform init time. While we’re using local-stack to simulate various things, this seems to suffice to get everything working.
