Downloading MPS plugin for IDEA

The documentation says that a zip file with plugin code for MPS into IDEA is available on the download page:

https://www.jetbrains.com/mps/download/?_gl=1*wxk3tg*_ga*NDg3MTEzOTU4LjE2Nzg1NDk1NzI.*_ga_9J976DJZ68*MTY4MDkwNjcyOC4xNi4xLjE2ODA5MDkzNTUuNTIuMC4w&_ga=2.152237241.14314912.1680802355-487113958.1678549572#section=mac

but there is only a .dmg download containing MPS there for Macs.   Where can one download zip file containing MPS plugins?
