DAX Formula who don't display duplicate value who have 1 hour difference

[ItSupportElm]

I have an issue that I can't resolve after some research.

Here my situation :

I want to delete duplicate data based on time who have just few second diffrence like the "IdUtilisateur" : 7971, and i want to keep the one who have comment , so the seconde row (18/01/2021 13:25:45 with the comment "Probleme de calendrier livraison")

I don't know if my example is clear. If you have any question ask me.

Thank you for your future answer

@ItSupportElm , One way if remove seconds from the date

New date = Date = date(year([datetime]),month([datetime]),day([datetime])) + Time(Hour([datetime]),Min([datetime]))

Other wise we need to create a flag based on the previous record, like 30 sec diff

new column =
var _max = maxx(filter(Table, [id] = earlier([id]) && [datetime] <earlier([datetime])),[datetime])
return
if( datediff( _max,[datetime],second) <=30,1,0)

remove 1
