Hi arturoeq,
You should be able to by first creating a subdomain (go to the domains tab in Plesk and click "Add Subdomain"). Once the sub domain is created just follow through the setup steps to get it installed.
*edited part*
Now looking through the docs a bit, since this isn't running as PHP or anything but instead with docker or NPM there might be a bit more complex. It's possible to do it through Plesk but I never figured out how it works, just know you still need to create the sub domain first (unless you're creating a different server elsewhere in which case you just need to create an A record in the DNS to point to the IP of the other server)
