Please Help !

I read that from (https://support.google.com/)

1. Enter the URL of the website you want to link to your Google Ads account, but make sure that you add one version with “www.” and another version without “www.” (for instance, “www.example.com” as well as “example.com”). You don’t need to specify HTTP or HTTPS.

I want to know , I have to add both version ( www and without www) or not to link search console and google ads account for paid and organic reports.

By the way , I just added site url with (www). so now am I able to see paid and organic report ?

You can add both but need to use one as your primary url and redirect the other url to primary url and you should be fine
