Missing Palettes

I have installed the @objectif-lune/node-red-contrib-connect palette and seem to be missing OL Connect Server and OL COTG Server nodes. They are grayed out when I view them. I downloaded it in the Node-Red application.
Can you tell me where I can get these?

Those are configuration nodes, not standard action nodes. You can look at them via the Configuration nodes option:
They will get created the first time you configure a standard Connect or COTG node since you need to specify a server connection for any of them.

Okay, that makes sense now. Thanks for the quick response, Phil.
