plot.overview not an exported object

[kinman1]

I've downloaded dlookr from CRAN, then your development version. I followed the Introduction and descriptions for overview and plot.overview for both versions
ov <- overview(myDataTable)

from the plot.oveview R documentation, both
plot.overview(ov)
and
plot(ov)

return the same error:
Error: 'plot.overview' is not an exported object from 'namespace:dlookr'

This feels like a bug, or something missing, although I could simply be missing the appropriate commands.
