Deploy multiple react apps in 1 Netlify projects, 1 domain and each react app is referenced by a relative path

I am trying to deploy multiple react apps in 1 Netlify projects, 1 domain and each react app is referenced by a relative path. example
netlify project - project-x
domain - projectx.com

react-app1 - projectx.com/react-app-1
react-app2 - projectx.com/react-app-2

I have a monorepo project of multiple react apps.
when the build command is complete I copy the build directory to a new folder with a shell script (set as publish directory on Netlify ui).

When I try to visit the relative paths, I get Page Not Found error.

Did you add a _redirects file to the final publish directory with the content:

/* /index.html 200
