Configure replication on the slave/replica server using the filename and position

[Bob Stoneman]

I'm running the following while setting up replication and I get the following error every time ?

CHANGE REPLICATION SOURCE TO SOURCE_HOST='10.50.11.11',
SOURCE_USER='cloud-repl', SOURCE_PASSWORD='*****************',
SOURCE_LOG_FILE='mysql-bin.000051', SOURCE_LOG_POS=40474608;

Replica Server error log:
2024-01-20T18:48:36.203277Z 75 [Warning] [MY-013360] [Server] Plugin mysql_native_password reported: ''mysql_native_password' is deprecated and will be removed in a future release. Please use caching_sha2_password instead'

I can't find anything on this anywhere. Any guidance would be appreciated :)
