Running Open-Liberty as a non root user

Question

We are trying to run an Open Liberty on a Red Hat server 7.9, however, the service will not start.

Systemd script which is starting the application is giving the following message:

OPENLP.service - IBM WebSphere Application Server
   Loaded: loaded (/etc/systemd/system/OPENLP.service; enabled; vendor preset: disabled)

Any idea as to what might be causing the above?
