Recently, arXiv:2210.05659 shows that a photon-axion like particle (ALP) oscillation can boost the survival rate of the high energy photons associated with the observed GRB221009A event. Here, we show that the proposed ALP is consistent with the electroweak axion with an anomaly free $Z_{10}$ Froggatt-Nielsen symmetry.Comment: 2 pages, 1 figure; matches published versio
