How to rename Angular Universal entry file to app.js and move it to the app root directory

So I have an Angular Universal SSR app which runs with node. The latest Angular and Universal versions as of 21/01/2021.

My hosting company allows me to run nodejs apps on my shared cPanel, so I would like to run my Angular app there. But the problem is they only accept the entry file app.js.

But when Angular SSR is built, it outputs this:

app-name
    -> browser
        - (all the browser files.)
    -> server
        -> main.js

Is it possible to output the ng build:ssr to this:

app-name
    -> browser
        - (all the browser files.)
    -> app.js

Then when I run the app it runs the default app.js entry file.

Thanks!
