I believe they are integrated into the handle and trigger. It’s not a switch that you turn on and off, just if you hold the gun in the proper way your are pressing in the safeties.
Just the trigger. A safety in the “handle” would be a grip safety, which some guns have but not Glocks (unless it is some obscure small run model, but certainly none of the common ones). It looks like an extra panel on the back of the grip which is squeezed into the grip when held.
