Unable to create databricks group and add permission via terraform

[soumiknow]

I have the following terraform code to create a databricks group and add permission to a workflow:

resource "databricks_group" "dbx_group" {
  display_name = "ENV_MONITORING_TEAM"
}

resource "databricks_permissions" "workflow_permission" {
  job_id = databricks_job.workflow.id
  access_control {
    group_name       = databricks_group.dbx_group.display_name
    permission_level = "CAN_MANAGE_RUN"
  }
}

I have the following databricks terraform provider:

provider "databricks" {
  alias                  = "workspace"
  host                   = local.dbx_host
  google_service_account = local.gcp_sa
}

Now, when I execute 'terraform plan', it returned error:

Error: cannot create group: failed during request visitor: default auth: cannot configure default credentials, please check https://docs.databricks.com/en/dev-tools/auth.html#databricks-client-unified-authentication to configure credentials for your preferred authentication method

If I use the 'host' & the generated 'token' values in '.databrickscfg' file, then 'terraform plan' and 'terraform apply' worked, but I have to use the 'google_service_account' directly to execute the group creation code.

Please suggest what needs to be done here in the existing provider so that the group and permission can be created via terraform.
