Use pg_recvlogical with --startpos option

I try to use pg_reclogical command at a specific offset, like that:

pg_recvlogical --start --slot connector --startpos=1/575D3AC8 -d mabase   -f -

or with 1/0

But it doesn't work, same as without startpos.

Command wait for new events but don't replay old events... do you know why?
