Hi ,

When we provide the authentication profile to Connect-REST, Pega generates an access token, which is then stored in the Data-Admin-Security-OAuth2-AccessToken class.

The next time Pega attempts to use the authentication profile, it first checks if there is an active access token available. If a valid token exists, it will use that token. Otherwise, it will generate a new token and store it in the access token table.

Let me know if you need any additional details or clarification on this process.
