Yes, and it is recommended. In the campaign, tick Append source attribution at the end of posts (recommended for copyright). Each post then ends with a small clickable Source link to the original article. Campaigns made by Auto Setup and the starter campaigns already have it on.
If you want the credit in a different place or wording, use the [source_link] tag in the campaign's content template. It is replaced with the web address of the original article, for example in a line like Read the original story: [source_link]. For most sites the campaign option is easier.
Crediting the source is fair to the publisher, shows readers where the facts come from and fits Google's advice to be clear about sources. The AI is told not to write its own source line, because the site adds the credit. A credit does not replace adding your own value, and you should only publish content you have the right to use.
