Proof Biden was fed lines during the debate?

After seeing a viral video claiming to prove that Biden was being fed lines during the Presidential debate, I decided to check it myself using my video software and the original source - https://www.youtube.com/live/-v-8wJkmwBY?si=HAWzk_qxNQOx_8IG&t=5369

Unfortunately, the claim is not true, which you can clearly see in this video.
