Hey there, and welcome to Apple Support Communities, John C Lin!
From our understanding, you have questions regarding whether you can remotely view Safari browsing history from another Mac using Screen Time.
Use Screen Time on your Mac - Apple Support goes over the options you have available with Screen Time. To view browsing history, you’d need to view it on that individual Mac, or you can use Content & Privacy options to restrict the content, downloads and more using Screen Time, which is listed in the article above.
That being said, you can provide feedback regarding this feature, and any suggestions you might have at: Product Feedback - Apple
Have a great day!
