Update Home Assistant Nodes

HELP! I just did a rather daft thing

I was looking thought this forum and found something i thought I would copy to look at how it worked. Unfortunately the flow included a a node for Home assistant, which I already have linked. Now I have a blue message to update all my HA nodes to a new schema, which I don't want to do. how do I get rid of this message?

Panic over i have fixed it.
