Addendum to “Combined constraints on first generation leptoquarks”

In this addendum to arXiv:2101.07811 we discuss the implications of recent CMS analysis lepton flavour universality violation in non-resonant di-lepton pairs for first generation leptoquarks. As finds more electron events than expected from background, prefers LQ representations $\tilde{S}_1, S_2, S_3, \tilde{V}_1, V_2\,(\kappa_2^{RL}\ne 0)$ and $V_3$ which lead constructive interference with SM. principle excess could also be (partially) explained by $\tilde{S}_2, V_1\,(\kappa_1^R\ne 0), V_2\,(\kappa_2^{LR}\ne \tilde{V}_2$ are interfering destructively, as would still right effect bins high invariant mass where new physics contribution dominates. However, these cases large couplings required excluded other observables. The $S_1, V_1\, (\kappa_1^{L} \ne cannot improve fit data compared
