What tool is needed to remove a Shimano HG-50 freewheel?

but I need a non-park tool tool. Something I can order from AliExpress.

I don't have enough reputation on bicycles to add comment to the duplicate question  (so my only option is to post it as question)
All Shimano cassettes, and all SRAM cassettes other than "XD" ones, have the same spline pattern.  If you search for "cassette lockring tool" you will find lots of compatible tools.  Virtually the only incompatible ones will be SRAM XD and Campagnolo, and they will be specifically labeled as such.
