FactSet: "Unrecognized function or variable 'fds'."

I've checked the requirements for FactSet https://mathworks.com/help/datafeed/data-server-connection-requirements.html and besides having a license, there are no other requirements.

I am running the following command on OSX

c = fds(login, password); % both login and password are defined

which returns

Unrecognized function or variable 'fds'.

Datafeed toolbox is installed, and the following command works

c = fred('https://fred.stlouisfed.org/');

Any help is welcome.
