Sqlserver publishes and subscribes, prompting the solution to the problem of "login failure for user 'sa'"

When I was configuring Sqlserver 2019 to publish and subscribe, I encountered a problem, prompting:

Login failed for user 'sa'. (Source: MSSQL_REPL, Error Number: MSSQL_REPL20015)
Get help: http://help/MSSQL_REPL20015

Later, the proxy security was set up to solve the problem. The process is as follows:

Select Publish Properties - Proxy Security - Security Settings:

Set both security settings to "by impersonating process account"

Then check the synchronization status, restart the release, and that's it.
