Noticed a bright object floating at high elevation. Appeared small and circular. I noticed it was at a high altitude.

Watched the metallic object slowly fly across the sky at high altitude from west to east.
It was apparent that it was not a small party balloon to me by how it flew without noticeably changing altitude and by the fact I could clearly see it above very high clouds.
Filmed video was able to pull a screen shot picture out of the video. When zoomed in it appears to be a cube with dark objects at the corners.
