Why can't I find flash options?

I have been looking at manuals on how to find the flash settings on my camera. According to manuals on this model of camera, I am supposed to have four flash options: auto, on, off, long shutter. But when I click the flash button on camera I only have two options: auto flash or flash off. This makes it so that I can't record with the flash on which is really crucial to what I'm using it for! Does anyone know if it's just the model I have or if there is another place I can find the flash settings? Thank you
