Troubleshooting Zapier Integration with Gamma for Presentations

Has anyone used Zapier to send something to Gamma to get a presentation? I have trouble mapping fields and I have had many random presentations turn up in my account with generic topics and specific other company generated documents. They are all sourced from API Keen to hear if anyone has been able to create from Zapier api… and map fields correctly. Any thoughts on the random presentations would be great too
