Short summary
This comment demonstrates that an intermediate phase with superradiant and antiferromagnetic order, and altered phase transition lines, IS present in the Dicke-Ising model, contradicting recent claims.

Key points
- The Dicke-Ising model exhibits an intermediate phase with superradiant and antiferromagnetic order.
- The order of certain phase transition lines in the Dicke-Ising model is different than previously claimed.
- These features are present for the parameter range investigated in Mendonça et al. [arXiv:2503.04961].

Abstract
Recently, Mendonça et al. [arXiv:2503.04961] investigated the Dicke-XXZ model and the Dicke-Ising model. For the latter model, their calculated quantum phase diagram contradicts claims about the existence of an intermediate phase with superradiant and antiferromagnetic order and the change in order of some phase transition lines, observed in other studies. In this comment we demonstrate that both features are indeed present in the Dicke-Ising model for the investigated parameter range in [arXiv:2503.04961].
