macOS Remote Screen Control Tool

My Background: I have a computer science background and have a lot of experience in web development but am not familiar with developing apps for macOS. I have a website for users to access running on a Linux server on DigitalOcean. I also have a Mac mini for running the to-be application. Goal: I want to build an application that will allow a user to control a Safari window remotely through my website. Requirements: - The user should be able to view and control the Safari window from their browser through my website (e.g. can scroll and click). - The application should delete history, bookmarks, cache, cookies, etc. after the user is done browsing. - The user should be limited to the current Safari window. They can't access other applications, open new Safari windows, change OS settings, etc. - This application should support multiple users at once with each user isolated to their own Safari window. - The application must prioritize security. The remote user should not be able to compromise the OS, applications, or other users in any way. Other Details: I am open to different approaches to solving this problem.
