Try to add firebaseui to theme's package.json and then run yarn from the root directory.

the issue is that: when I go to src/themes/default and do yarn add firebaseui it adds it to package.json, but when I do yarn install it's not creating node_modules in src/themes/default o_O yarn --cwd src/themes/defaul install also not creates node_modules How I should install those dependencies then? I need to manage workspaces somehow? I have yarn 1.22, maybe I should use yarn 2? I can use npm fot that and then it works but would be better to use yarn it whole project
