How to use Oauth in the application.properties file?

I had an application.yml file using Oauth as follows:

oauth:
  enabled: true
  all-in-one: true

But now I need to use the application.properties file and the structure is different. I thought it was just like this:

  oauth.enabled= true
  oauth.all-in-one= true

But it does not work. I would like to know how to leave what you have in the application.yml file in the application.properties file structure
