How to reuse the authentication token from one multi syntehtic tests to another multi test using terraform in datadog

HI,

I am not sure its issue with Datadog Synthetic tests or its my poor understanding of Terraform Datadog documentation

I have created synthetic multi tests and generated authentication token ( lets say test name as aunthetic_token_generation) using extracted value as below

extracted_values = 
        {
          name = "token"
          type = "http_body"
          parser = {
            type             = "json_path"
            value            = "$.access_token"
          }
        }
      
HOW TO USE THE EXTRACTED VALUE TO OTHER MULTI-TESTS ???

Now I need to access the token into another multi tests and pass it as Bearer token as request header

request_headers = {
        Content-Type    = "application/json"
        X-Cricut-Client = "DD-synthetics"
        Authorization   = "Bearer {{ ${var.auth_token} }}"
                           OR
       Authorization   = "Bearer {{ AUTH_TOKEN}}" /// This is creating new global variable
      }

I have tried assigning to global variable as below and try to assign and accessing it but no luck and also with local variable

resource "datadog_synthetics_global_variable" "aunthentication_token" {
  name        = "AUTH_TOKEN"
  description = "Description of the variable"
  value       = ""
}

Is there way to extract and assign toaken value from one to many multi tests using terraform ??

Thanks in Advance

Any solutions much appreciated
