Intergration with Okta using terraform

Hello Sentry

I am trying to use terraform to integrate Sentry with Okta:

resource "okta_app_saml" "sentry" {
  label             = "Sentry"
  preconfigured_app = "sentry"

  app_settings_json = jsonencode(

      baseUrl  = "",
      org_slug = "mycompany"

  user_name_template = "$${}"
  depends_on         = [okta_group.groups]


I can pass baseUrl but I can’t pass org_slug.
Can you advise the correct name for the field?
Or maybe someone did something like this before?
