Remove node-red-node-google

I have not succeeded to get credentials for node-red-node-google

I want therefore to uninstall that package but I cannot do it as the 2 of its nodes (google-credentials and google-api-config) appear to be in use.

What can I do to remove the full node-red-node-google package?

If you deploy do you see a popup saying there are unused configuration nodes with a link to click? Do that and it will show you them, you can open them and then Delete them there. Alternatively look in Configuration Nodes under the hamburger menu and you should find them there.

Thanks, the configuration node was the solution
