REST MOCK Service: No WebUi

With the free version of SoapUi 5.7.0 I built a REST MOCK Service.
With the graphical interface of SoapUi it works correctly.
Now I have generated the war file (rest.war) and deploied on Tomcat 9.0.63 + JRE 9.0.4.
Now selecting on "Tomcat Web Application Manager" the entry: /rest
I get HTTP 404.
Is posisble with SoapUi 5.7.0 (free version) display the WebUi for the REST MOCK Service?

Thanks.
