How do I play this mordent ?

[pakkun]

Hello ! Just started another Chopin Nocturne (op.32 no.1)

Just to be sure, how do I play this mordent on a double note ?

Is it correct to play the double and then the other two of the mordent with a single note ?

Like 32 - 4 - 3 ?

Thanks in advance

After watching some videos I think I got it !

I should play the mordent first and then the double note : 4 - 3 - 32

I'd start the mordent on the beat, synced with the bottom note.
