Environment variables cannot be passed to extension

[ShaneMazur]

Unable to provide a token stored as an environment variable to this extension (templater = dbt, dialect = databricks) :

• The extension does not inherit environment variables defined by "terminal.integrated.env.osx" . DBT's vscode extension uses this. Ex:

      "terminal.integrated.env.osx": {
          "DATABRICKS_TOKEN": "${env:my_token}"
      }

• The vscode settings for sqlfluff, specifically "sqlfluff.env.environmentVariables", don't seem to support pulling in environment variables. Ex:

      "sqlfluff.env.environmentVariables": [
          {
          "key": "DATABRICKS_TOKEN",
          "value": "${env:my_token}"
          }
      ],

• Even using the "sqlfluff.env.useDotEnvFile": true does not work as intended using a .env file like below. Ex:

  # .env
  DATABRICKS_TOKEN=${my_token}

How can we configure the extension to inherit an environment variable in some way? (for obvious reasons I wouldn't want to hardcode a token in my settings.json)
