does hubspot-api-ruby include the associations_api?

[max-pi]

I'm trying to create a company and add a contact

I can do

contact

contact = HUBSPOT_CLIENT.crm.contacts.basic_api.create(simple_public_object_input_for_create: contact_properties)

company

hubspot_company_result = HUBSPOT_CLIENT.crm.companies.basic_api.create(simple_public_object_input_for_create: company_properties)

^ both the above work

Then I tried to associate with

assoc_result = HUBSPOT_CLIENT.crm.companies.associations_api.create(
  hubspot_company_result.id,
  "contact",
  hubspot_contact_id,
  "COMPANY_TO_CONTACT"
)

but I see

NoMethodError: undefined method `associations_api' for #<Hubspot::Discovery::Crm::Companies::Client:0x000000010f450280

I'm looking through docs here:
https://www.rubydoc.info/gems/hubspot-api-client/9.6.0/Hubspot/Crm/Companies/AssociationsApi#create-instance_method
