I'm not even 70% sure about the chords, as I'm trying to play it now my guess is that she didn't use power chords
I think she played variations of chords. So for the A chords, I'm not sure, sometimes I can hear Am, A4 or simply A (in the chorus part). And for the F chords, I play just the main note (1st fret, 6th string) and not pressing any other string.
Try it out and see if all of these make any sense
(Intro)A4 C7M Am/A4
VerseAm/A4 - Fm - G6
G6 - Fm x2 (by the second time, maybe there's a C7M just after the Fm, before starting over the verse)
Am/A4 - Fm - G6
G6 - Fm - Dsus2 (add the Dsus2 just before going to the chorus)
Chorus -
A/A4 - Dsus2 - C7M - G6 (same as the end)
