Please help trying to tab out this little riff (synth in chasing pavments)


Im doing a cover of this song and I just would really need some help! i cant seem to figure out what the synth is playing in the chorus of 'chasing pavements' could anyone help with a quick tab? Its really not long and i would so appreciate it ALOT. I know the progression of the chorus is

Ab9, GM,CM7,FM7sus4,ab9,gm,g7,ab9,gm,cm7,fm7sus4,fm/ab,g7

anyone help me out? the synth starts at 0.57

or alternatively somethign that would really play nice with behind the guitar, maybe just 4 chords and their tab thank you alot
