How Does Data Retention Work for API-Generated Visuals Deleted in Gamma?

Hi, I have a question regarding the api/mcp connection, and how the data retention works with Gamma. If an api generated visual is deleted, and emptied from trash, what happens to the data that was passed through the api, as well as the data that was of the visual. This is important to us due to our clients being very strict with their business data, making Gamma a non-viable solution if the retention is less favorable. Let me know when you get a chance, thanks!
