How to Rename Gamma Deck Titles Programmatically via API

Does anyone know how to write or change the saved gamma deck title name using the API or programmatically? We have over a hundred decks, but they need the four-digit number in front eg "1125_Intro". What I'm getting now is just what looks like an AI-generated title. Does anyone know where the file name is generated from? I don't need the content in the slide deck to change, just a deck name that is saved in the folder.
