It is purely illustrative (of course if you need this model you can add it)

since it is in there, it should work for creating (post) and reading (get request), as mentioned in the document, right?

no its a mistake that it's in there

then how can I try out this no code modeling feature? or what's the status of this no code modeling?

You can write a new mode

Thanks. Yes, I think I got partial features working for a new model. the other partial which doesn't work yet is due to my local ES setup.
