Redirect after login to the use of a specific wordpress plugin on WPMU

I'm creating a site with wpmu where people can create their own site/cv and I'd like to find out how to redirect users to the plugin page after login.

Finding a code to redirect is not a problem, it's the url that I can't create.

I've created fake accounts to test and the url to access the plugin when I'm logged in is like this –https://www.site.com/janettedo/wp-admin/admin.php?page=rbuilder\_main
