How to disable users from being able to view app through regular browsers in express / electron app

I have an express server that serves my angular front end at http://localhost:9000

I'm using electron as a desktop client.

I want to force users to view the application through electron and only through electron. I don't want users to have the ability to browser the application through any other browser.

Is there any way to disable the ability to access the app through a regular browser?

I've attempted to find information regarding this but have come up short.
