How to add agent to Solar Winds using API (Agent is already installed on the server manually by other methods)

Hi,

I have a bunch of Linux servers which we have installed the SolarWinds agent on and they were configured for server initiated connection.

Now I would like to use the Solar Winds API so I can add these agents into the console. Same as how we would do it manually on the web interface like the below:

Is there such API available? (preferably using PowerShell or Python)..

I've tried looking at this schema reference SolarWinds Information Service v3.0 Schema Documentation  and also referred to the SWQL Studio but I cannot seem to right the right method/function to call?..

Thanks in advance guys!
