Best way to deploy application extension to Prod

Summary:

Hello

Accross diferent documentation, I saw there's 2 way of deploy application extension from Non-Prod to Prod instance, so I need some clarification:

• Using Manage extension life cycle
• Running manually the Production a pipeline
  

For the 1rst one, I saw that need to add production environment by selecting the OAuth 2.0 as the Authorization Type, to using it, is it correct ?

I added environment by usic Basic as Authorization type and in life cycle I have this message

Whereas by adding a Prod environment with OAuth 2.0 and adding my credentials, I have this message

But in another project, I also deployed application extension by creating a prod Workspace, merge request, and a Prod pipeline and my extension were successfully deplyed to Prod environment
