The study refers only to KF94 (Korean Filter) masks: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10112860/ While it suggests to open a KF94 and not worn it for at least 30 min, it also states using masks designed to filter out at least 95% of particles (KF94, N95, FFP2), is highly recommended for preventing the spread of COVID-19.
