Problem Integrating Trino with Ranger Plugin

[just-NPT]

I am encountering an issue while integrating the Trino Ranger Plugin. I have enabled the plugin on Trino, which I can verify as shown in the screenshot below:

However, in the Ranger UI, I am unable to create a Trino service. The following error appears:
Trino failed to find service class org.apache.ranger.services.trino.RangerServiceTrino. Resource lookup will not be available. Please make sure plugin jar is in the correct place.

My environment details:
Trino version: 454
Ranger version: 2.4.0

I have updated the servicedef file as instructed in the official Trino documentation on Ranger access control (https://trino.io/docs/current/security/ranger-access-control.html), but the issue persists.
