The song is in E minor 4/4; I transposed it down to D minor to give it a bassier feel. But yes, except for the prechorus (and a minor variation during the chorus), it’s same riff for the entire song.
There are plenty of tabs available on the Web, should you want to go that route.
Maybe I got it wrong then, for sure about minor, bad guess, have to hear the tones better plus one video said most pop, soul, etc., are in minor.
But was I wrong? I thought it started in E at first, then did a chord change into D.
