After the publication of our paper [1], the authors found that Figure 5(c) was using an incorrect data file, which has been corrected here.

Figure 5: 
The computed cavity spectra using the dipole gauge (left) and Coulomb gauge (right), with a flat DOS [κ (ω) = κ, panels (a, c)] and an Ohmic DOS [κ (ω) = κω/ω

c
, panels (b, d)] using the generalized master equation [see Eqs. (A9)–(A10) in Appendix A]. In both cases, the effect of the gauge correction (solid lines versus dashed lines) is dramatic. We use the same parameters as in Figure 2 of the main text, with incoherent driving, and parameters η = 0.5 and κ = 0.25 g. Notably, in all cases, regardless of the spectral function, the corrected dipole gauge and corrected Coulomb gauge results are identical.
