Youtube Music Recommendation update

[llama-spec]

I need help i am making a music app for myself (for my resume) i noticed something that when i listen to a song like 3, 4 times the song would start to appear in my Speed Dial (Listen again) section so i was thinking like how they do this, updating the recommendation i checked that whenever i listen to something it gets added to my Youtube music history. So i thought by adding to history they update my Listen again section. I Know that this api has a method to add item to history so i tried that with this api i added a song 4 times in my history (obviously with authentication ) but it didn't appear in my Listen again section. So for the testing i opened my Youtube music app in my phone and in my browser in my pc i listened to a song there 3 times and there it was in my Listen again section. So i opened my network tab to see what they are doing to monitor i don't know i found this api/stats/watchtime endpoint i think this is doing something. SO IF SOMETHING LIKE THIS EXIST IN THIS API TELL ME CUZ i need their recommendation and it should update when i play song on my app just like in there app. please i have been working on this app for like 8 months(solo).
