Aha I see now how it's done. Basically:

1. add dependency in go.mod
2. go mod vendor stuff
3. register it in components.go explicitly

Curious, how did you generate the README.md update? (If there is an instruction documented somewhere, a link would be perfect)

(Next time if I need something, I can try not to bother you writing it out and just ask you to review it

There's instructions on updating the component here: https://github.com/observeinc/observe-agent?tab=readme-ov-file#adding-new-components

its actually a little complicated since we need to add it to the manifest and then install the ocb tool and use that in the makefile command to generate the new files and move them to the right places. The README.md i'm manually updating by hand using https://www.tablesgenerator.com/markdown_tables
