no Alert function, graph issues

[j2l]

I'm trying to learn noflo and export to code
Your 1st tutorial https://docs.flowhub.io/getting-started-browser/ is a simple alert.
But alert is not present in the menu:

I also noted that it's not present in your hosted version. I might have missed something because github issues related to "alert" is not replied about this detail. Would you please point me to the correct tutorial pages and/or list of existing functions?

Graph:
As you invite I installed the-graph but I'm getting errors in console and window:
