How to correctly replace 'default_authentication_plugin' with 'authentication_policy'?

I have MySQL 8.0.33 on Ubuntu. In the error log, I see the following warning: > [Warning] [MY-010918] [Server] 'default_authentication_plugin' is deprecated and will be removed in a future release. Please use authentication_policy instead. In my mysql.cnf file, I changed this line: default_authentication_plugin= mysql_native_password to this line: authentication_policy= mysql_native_password but it broke my application: when the application tries to connect to the database, it gets an error Could not connect: The server requested authentication method unknown to the client. What is the correct way to solve this issue and remove the warning, without making too many changes to the application?
