I need help for the tabs of this song (Bass)

The song is every breath by boyce avenue.

I'm a beginner so I might some need help for this. I would really appreciate if someone could help me tab out the bass riff for this song...

P.S: I tried googling it but there wasn't any bass tabs for this song.
