Need to understand terraform working with plugins

I have terraform installed on my local mac where does plugins get stored. I created a folder called as plugins in ~/.terraform.d/ but still don’t find any plugins getting stored any help is appreciated

@sthapar , Have you run terraform init so as to initialize the plugin?

Third-party providers can be manually installed by placing their plugin executables in the ~/.terraform.d/plugins directory. Terraform init will search this directory for additional plugins during plugin initialization.
