I need to create a desktop program for Windows and Mac. The program puts extensions in Google Chrome and Microsoft Edge browsers

I am looking for a developer to create a desktop program for Windows and Mac that adds extensions to the Google Chrome and Microsoft Edge browsers. The primary purpose of this program is to enhance productivity, so it should only run on the specified browsers. I do not need the program to display any web content. The right person for this project should have experience developing software for both Windows and MacOS as well as expertise in Chrome and Edge extensions. If you believe you are up to the task, I urge you to submit a proposal
