How do i enhance generative fill content when working in a high rez image?

I was just using generative fill on a selected portion of my image, and during processing, I got a popup message while that said something to the effect of “working with high res images? Select enhance on generated fill content to upres it.” However I don't know where this tool is in PS! The generative fill process went so quickly that I only had a couple seconds with the message on my screen before it was gone, so even if it told me where it would be, I didn't have time to read the whole message before the tip was gone! If someone could point me in the right direction to find this tool I would greatly appreciate it!
