There is a way to do it without the integration too.
I added frequently used settings pages to my sidebar (Entities, Automations, Integrations, etc.) Plus a one-click Restart button - Share your Projects! / Dashboards & Frontend - Home Assistant Community (home-assistant.io)
That was the case many years ago.
So many who installed HA many years ago probably installed Node Red to get around some issues and just have it still due to some automations have not been ported over yet.
I have this.
I don’t remember when I last added a new Node Red automation. I only use it now for things that is far easier than HA automations.
Like getting data from an API and manipulate it before adding it to a sensor.
Or reading files that is not possible in HA automations.
