A spectrum with exposure time 4x1200 s (grism #20) was secured starting on 2022 Jan 1.81 UT (14.3 hr after the GRB), under good conditions, and covering the wavelength range 5600-10200 AA. A very clear trace is detected from the afterglow continuum. A deep, broad trough is detected around 6800 AA, which we interpret as due to damped Lyman alpha. A number of narrow absorption features are also clearly visible and allow to determine accurately the GRB redshift. We identify, among others, N V, S II, Si II, Si II*, O I, Ni II, C II, Si IV, C IV, Fe II, Fe II*, and Al II, all at a common redshift z = 4.618. Our results thus fully confirm the finding of Fu et al. (GCN 31353). Nice year start for GRBs: happy 2022 to all GCN readers!",
