1.17.30 Mac installer

I'm seeking a Minecraft Education 1.17.30 Mac Installer if anyone has one?

Our school computers are running on 1.17.30 as we run lots of multiplayer events at our school (and 1.18 is plagued with multiplayer errors at the moment). I can't seem to find an archive of the old installers :(

If anyone has the dmg by some amazing circumstance, can you please send it my way?
