Can't do explain() traversal step using Gremlin-Python ..

Hi I just started messing around in gremlin-python this week, so likely to be doing something wrong with g, but as mentioned on twitch, I'm unable to add an explain() step to one of my first traversals.
i start with g a connected graphTraversalSource and perform the following
vertex = g.add_v("my_vertex").next()
vertex = (
    g.V(vertex)
    .property("~supernode", True)
    .property("foo", "bar")
    .property("baz", "biz")
    .explain()
    .next()
)

when the explain step is reached (or added in as this behaves fine without explian), i get the following error:
TypeError: 'GraphTraversal' object is not callable

so i try removing the parens after explain, but that only puts [values explain] at the end of the traversal
if i change explain to a step that certainly does not exist (foobar) and get the same error
trying without next / substituting next for value_map or something has no effect..

if i search my local installation of gremlin python (recently updated from 3.6.4 to 3.7) i get no results..
λ cd ~/.local/lib/python3.10/site-packages/gremlin_python ; grep -rn explain .
