begin_wal=00000029000007D1000000AB
begin_xlog=7D1/AB011228
end_offset=3770760
end_time=2022-04-06 16:21:57.718591+02:00
end_wal=00000029000007D1000000AE
end_xlog=7D1/AE398988

Assuming it was performed correctly at the end of the recovery the database will be current with the last transaction committed before the end time.
