Hi and welcome
This song is at a fairly quick pace but is really quite simple once you get the hang of playing the bass note and then finishing the chord in time. Rather than get into complications with a metronome, setting a constant tempo of 140 and striking the appropriate string(s) in time will be simpler.
Most of the time I use the metronome on Google - its just a solid time, no accents etc.
Good luck.
This year the diet is definitely gonna stick!
