Gemeni Flash Image Generation 2.0 Success with Make.com but Not Upload to Drive?

Please help me! I’ve successfully called the Gemini Flash Image Generation API, and now I’m trying to figure out how to convert the image from Base64 to Binary so I can upload it to OneDrive.

The image format from Gemini comes with a MimeType and Data containing the Base64 string. I’ve looked through many documents but still haven’t found a way to do it. Please help me
