Salesforce splunk integration- Why don't we see any logs?

[rajwdc]

We are configuring salesforce splunk integration in our salesforce sandbox. We followed the documentation provided by splunk and have added the Salesforce add and was able to authenticate successfully.  We have configured the inputs with the oAuth authentication and validated successfully.  However we do not see any logs captured in our splunk and additionally we see the following in the logs, 

Splunk Log : 2022-10-10 20:54:56,778 INFO pid=28611 tid=MainThread file=input_module_sfdc_event_log.py:collect_events:333 | [stanza_name=Test_Event_Logs] Collecting events started.
2022-10-10 20:54:56,779 WARNING pid=28611 tid=MainThread file=sfdc_common.py:key_configured:223 | [stanza_name=Test_Event_Logs] Salesforce refresh_token is not configured for account "Sandbox_POC". Add-on is going to exit.

any advice is greatly appreciated
