How long can I stay in HK after my working visa expires?

I’ve been living in Hk for 2 years and my working visa is expiring at the end of May. Does anyone know for how long can I stay here as a visitor after my visa expires? I’d like to stay for at least another 2-3 months. I know that before Covid people used to leave Hk for a day and then come back for another 3 months with a tourist visa, but does anyone know how it works now? Couldn’t find any info online. Thank you!
