Action doesn't work with Yarn 3

[kachar]

I'm using yarn berry v3.3.0 in my project and seems that the action uses syntax for yarn classic 1.x

yarn set version berry

Run plasmicapp/plasmic-action@master

$ yarn add -W @plasmicapp/loader-nextjs
Unknown Syntax Error: Unsupported option name ("-W").

$ yarn add [--json] [-E,--exact] [-T,--tilde] [-C,--caret] [-D,--dev] [-P,--peer] [-O,--optional] [--prefer-dev] [-i,--interactive] [--cached] [--mode #0] ...
