Help needed with restore variable

i woudl really appreicate it when you give some help with the ReStore Variable.

In the firestore restore variable there is filled in the path “stape/restore”.
But when using that, there is an error in the log with “path should point to collection”.

When using the collection as path there wpuld be a lot of automatic document ids.

In the help text of the variable there is some text added that you could chosse a key, but i tried so much and didn_'t figure out how i would have to do this

in my attached example would it be possible to store the data in

view_item / IDENT / … ? But how do i have to do that with the path or the variable in the restore varibale?

Thanks again!
