timestamp, date formatting,csv-file

Hey Community,
Due to problems regarding xes file import, I converted the xes file into a csv file, for this I had to redefine the time stamp attribute of the type date into a string, this time stamp is now in the string format of an xes file, if you have a Idea how I change this date format so that I can also use these timestamps in my event logs for Process Mining?

the timestamp format seems like that:

2021-03-23T15:36:21.558+0100

Thank you for your Help

link of csv-file: https://github.com/faruk81/xes-converted-to-csv

suppressPackageStartupMessages({
  library(lubridate)
})

string <- "2021-03-23T15:36:21.558+0100"
ymd_hms(string)
#> [1] "2021-03-23 14:36:21 UTC"

great, now I have to make this change for the whole csv file ... do you know how it is possible to change all timestamp attributes so that they got this format?

suppressPackageStartupMessages({
  library(readr)
})

DF <- read_csv("https://raw.githubusercontent.com/faruk81/xes-converted-to-csv/main/datetostring3.csv")
