  The cross-correlation of cosmic voids with the lensing convergence ($\kappa$)
map of the CMB fluctuations offers a powerful tool to refine our understanding
of the dark sector in the consensus cosmological model. Our principal aim is to
compare the lensing signature of our galaxy data set with simulations based on
the concordance model and characterize the results with an $A_{\kappa}$
consistency parameter. In particular, our measurements contribute to the
understanding of the "lensing-is-low" tension of the $\Lambda$CDM model. We
selected luminous red galaxies from the WISE-Pan-STARSS data set, allowing an
extended 14,200 deg$^2$ sky area, that offers a more precise measurement
compared to previous studies. We created 2D and 3D void catalogs to
cross-correlate their locations with the Planck lensing map and studied their
average imprint signal using a stacking methodology. Applying the same
procedure, we also generated a mock catalog from the WebSky simulation for
comparison. The 2D void analysis revealed good agreement with the standard
cosmological model with $A_{\kappa}\approx1.06 \pm 0.08$, i.e. $S/N=13.3$,
showing a higher $S/N$ than previous studies using voids detected in the Dark
Energy Survey data set. The 3D void analysis exhibited a lower $S/N$ and
demonstrated worse agreement with our mock catalog than the 2D voids. These
deviations might be attributed to limitations in the mock catalog, such as
imperfections in the LRG selection, as well as a potential asymmetry between
the North and South patches of the WISE-Pan-STARSS data set in terms of data
quality. Overall, we present a significant detection of a CMB lensing signal
associated with cosmic voids, largely consistent with the concordance model.
Future analyses using even larger data sets also hold great promise of further
sharpening these results, given their complementary nature to large-scale
structure analyses.
