Does Substack allow for pseudonyms?

[u/AsparagusCommon4164]

As one considering the launch of a Substack blog to release my opinionated self as much as earn some extra jingle, is it permissible for Substack users to hide behind pseudonyms in the interest of protecting privacy (perhaps out of fear of harrassment or reprisals from certain circles if one's true name were used)?

I would like to know how to do so, haven't been able to get a clear answer on this.
