Wix-crm-v2 documentation for updateContact() vs Wix Studio mismatch

Question:
The documentation for wix-crm-v2 updateContact() has “revision” as the third argument, whereas in Wix studio, revision isn’t one of the arguments (see the image). There doesn’t seem to be a way to pass in the revision.

function updateContact(
  contactId: string,
  info: ContactInfo,
  revision: number,
  options: UpdateContactOptions,
): Promise<UpdateContactResponse>;

        // revision 取得
        const elevateGetContact = elevate(contacts.getContact);
        membersContact = await elevateGetContact(memberRes.contactId);
        console.log("😄", "membersContact:", membersContact);
        // 更新
        const elevatedUpdateContact = elevate(contacts.updateContact);
        contactRes = await elevatedUpdateContact(
          memberRes.contactId,
          paramContact,
          membersContact.revision
        );
