They must have limbs skilled enough to handle and construct this technology, a complex communication system, and a binocular vision system (for this reason the most used in all species) to perceive their environment. The humanoid shape is one that best fits these maxims and therefore it is quite possible that an advanced species would also have a more or less similar shape.
Elephants meet all of these criteria as well. A complex limb (their trunk), a complex communication, and binocular vision (although I don’t see why this is necessary).
Complex limb? Let me see an elephant tie a granny knot. Maybe with training? OK. Do a square knot.
Complex communication? Elephants have communication skills on par with a 3-4 year old human. An intensely trained dog might top 200 words. My vocabulary is an easy 50,000 words. Yours is too.
Binocular vision is a must, that’s a given. Damn near every animal on the planet has it, even some worms.
