Triangular UFO in Zimbabwe.

I recently saw a triangular UFO that hovered in the sky above the clouds for over 28min in the same position before I eventually went back in the house,I use a samsung A03S so I could record a clear video because the camera has low resolution,I took some images and the interesting thing is that I live in Zimbabwe,Bulawayo where there is zero advanced military tech.The object was above the clouds as it was not visible when they passed.I didnt post this on the same day because of the lack of clarity of the object.
