Can dims be auto-inferred during to_dataset?

[ahuang11]

import xarray as xr
import xarray_sql as xql

ds = xr.tutorial.open_dataset('air_temperature')

ctx = xql.XarrayContext()
ctx.from_dataset('air', ds, chunks=dict(time=100))

clim = ctx.sql('''
  SELECT
    "time", AVG("air") AS air
  FROM
    "air"
  GROUP BY
    "time"
''')

clim_ds = clim.to_dataset()

To my surprise: ValueError: dims cannot be inferred: no registered Dataset has all of its dims present in the result columns. Pass dims=[...] explicitly.

I imagine the value for group by would become the dim here?
