Caption: Figure B1.

NIR spectra of SN 2018bsz. We extracted the SN position in the SINFONI data cube obtained at +17 days. A narrow Paβ is clearly detected, which is from the host H II region. No broad emission from the SN has been seen, confirming the hydrogen-poor ejecta at peak brightness. The X-Shooter spectrum was taken on +383 days; no trace from the SN has been detected. The spectra shown in this figure are provided as Data behind the Figure.
