Appropriate way to add node-red-contrib-os

[Vladdy]

Hi
New to this. Searched forum but couldn't find what I think I'm looking for...

I want to read RPi system statistics into Node Red embedded, CPU utilisation, temp, etc. Found this example:  System statistics of Raspberry Pi (flow) - Node-RED (nodered.org)
However this requires that I install the following:

Code:

npm install node-red-contrib-os

What is the correct way to do this for Node Red embedded?
And how might I monitor the success or failure thereof?

I thought I could add it under 'Npm modules to make available' in the Node Red config under SignalK but the documentation on this is very sparse.
Thank you in advance.
