I don't know exactly what's in the safety token, but we do know that it's grayscale and low resolution. Allow me to be hypothetical for a moment; let's assume for a moment that the image has all chroma data stripped, it's downsampled to 1 megapixel, and then compressed to around 100 kilobytes using JPEG or HEIC. That would be sufficient for performing careful human review but would completely demolish any steganography.
