Using Sharpen AI in PS

Now that Adobe has added both Denoise and Sharpen AI what is the suggested way to use that? Not any separate Topaz apps that are purchased. The two that are in the filters that are partnered with Topaz that require premium credits.

I don’t need information on Denoise AI because I have access to Adobe Denoise AI, I just need information on Sharpen AI. There is no trial period and there are no settings to choose from. It just runs and I don’t want to waste credits on testing from the start.

I have been all over the internet and youtube and all information is for the plug-in apps. I’d like to know if I should do all of my sharpening first and then run it. Or should I just leave sharpening at the default settings, run it and fine tune later. Or should I turn Sharpening completely off, run it and then fine tune.

As my usual workflow with other 3rd party I plan to use at the very end.

Thank you
