Trying to set up a standalone agent, but no data showing up

We're running ES 8.14.2. I'm trying to set up a standalone agent (running Windows) for testing. I successfully installed the agent, and used the config file generated by the ES GUI (after populating the credentials). I can see traffic being sent to the ES node on the network, but I don't see any data (or perhaps I'm not looking in the right place). In Integrations > Elastic Agent > Assets, there are several dashboards for viewing agent data. However, they are all empty. What am I doing wrong?
