As best as I can tell from the video,
On the first off the lip / turn down, it seems you are just using your back hand/arm for balance, recovery and to not fall off. It should be used for drive and to twist the body away from the face.
On your attempted pumps, Yes you are moving your hands/arms, but they're not done purposefully. They're just being swung back and forth. You need to listen to the wave. You need to be timed to its rhythm.

You need to slow down. You need to learn how to trim. You need to learn to set your rail and release your edge. You need to learn how to roll from inside rail to flat bottom to outside rail and back. And these all are very hard to learn if you went too short too fast.
