Imported nodes in nodered are not visible

Hi when trying to import flows via the import function it is shown that the nodes are imported but I cannot see them anywhere.
What am I doing wrong or missing.
Could not find it in the docs. Exporting my flies is working fine as well.
Thank you

This is the flow that I would like to change to my needs but it unfortuately does not work as desired.
https://flows.nodered.org/flow/97d1ad82740d1c0ca1e7d1936862969e
I copied the node and pasted it in my NodeRed via the import function but it does not show up in my flows, although it says that it imported 14 Nodes and 1 subflow bul I cannot see them anywhere. Any help
would be appreciated.

It would be under the subflow section.

unfortunatly I could not find it anyhere arround there either. It seems as if it is not visible but is imported anyway. However I am not able to change the import to my needs.

Ah it is on the other side. Great. Now I know what the guy is doing. And yet it seems that there is a much easier way to activate certain scenes using nodeRed, just like I am able to do in Automations.
So basically what I did in Automalions using .yaml I would like to achieve ine NodeRed

This is just to see what I did as a test.
