Direct answer
Do not assume a separate negative-prompt field exists. Google’s current image-generation documentation emphasizes natural-language instructions and image editing; express exclusions as explicit constraints, then test whether the selected interface honors them.
Search volume is an observed demand signal; it does not prove that a tool is best, free, available in every region or suitable for a project.
