Smoothen 2 video (8 sec each) clips of jittery camera swipes

I seek assistance editing two brief moving camera video clips to reduce roughness in motion. The 2 clips each last approximately 8 seconds and were captured using an iPhone 12, resulting in some jitteriness. A video editor is needed to apply smoothing techniques that blend and stabilise the footage in order to achieve fluidity and continuity. Please view the footage prior to work to see for yourself if you can manage to provide a competitive result for this sequence for a Youtube music video.. I wukk attach footage to message to see for yourself if you are able to do this. Furthermore, I believe it may be advisable that you have AI software which can tackle the jitteriness. I have tried with Premiere Pro and I have failed, so you may need more specialist software. The result must not compromise on the quality of the current material, it is just the jitteriness that needs to be eliminated in order to provide a smooth flow.
