Updating custom wazuh agent

When i run non-custom agents, i can see agent-versions in the wazuh dashboard at /app/endpoints-summary

If there is an outdated (online) agent, i can update the agent easily and this is great!

Unfortunately i need to run custom agents in order to update the policies constantly (Europe is in the middle of implementing the NIS2 directive). Does this "outdated agent" detection system in the dashboard still work for custom agents? How does the Wazuh Dashboard know what the latest custom version is? How does the agent that gets a signal from the Wazuh Server know where to get it's update (as this is no longer the Wazuh repo, but my own repo with releases)?

Thank you!
