no clear way to pass api_key to provider

[mhmdio]

I have a big enterprise clients who is using Netskope and I'm introducing them to terraform, and now we are using this provider.

There is no clear way to pass token to provider, what I did was to look into the source code to figure it out

provider "ns" {
  server_url = "https://xxx-xxx.eu.goskope.com/api/v2"
  api_key    = "XXX"

}

Is there a way to pass this as ENV variables?
