Why is the Canon camera flash not synchronized with the studio flash?

It should be a camera built-in flash, with a photographic studio flash, right? If so, check the settings of the camera's built-in flash. If the built-in flash can be set to manual, you can use the photosensitive flash in the studio. ETTL can only use Canon lamps, not other flashlights.
