Subject: Could we go back in a replication slot?

Hi, community,
The START_REPLICATION command accepts a lsn parameter, but according to the
document that replication "starts at either WAL location XXX/XXX or the
slot's confirmed_flush_lsn (see Section 54.19), whichever is greater." I
wonder if there is a way to go back, like a command to set
confirmed_flush_lsn to a previous lsn.
I am asking because I may need to replay the replication messages to Kafka.
Sincerely,
Xiong Ding
