I need help running this example code that Supertoken has: https://github.com/supertokens/supertokens-auth-react/tree/master/examples/with-one-login-per-subdomain When I run the npm i && npm start the server runs in an error of

> supertokens-auth-react@0.33.1 front
> (cd ./examples/for-tests/ && BROWSER=none PORT=3031 npm run start)        


> supertokens-auth-react@0.33.1 server> cd test/server/ && START=true INSTALL_PATH=../../../supertokens-root NODE_PORT=8082 node .

'BROWSER' is not recognized as an internal or external command,
operable program or batch file.
ERROR: "front" exited with 1.
