Transcribtion?

Hello there!
I am a beginner bassist, started playing a year ago. As you all know, beginners are not that good at transcribing or guessing which note is being played. So, I found a song with a cool bass line that I would like to learn. But I can not find a sheet music or tabs for the song.
Can anyone transcribe the song for me?
The song called Poster Girl by Zara Larsson. I found the instrumental version:

Is there any good transcribtion programs you recommend (not paid)?

Thanks in advanced!
