Owner-Committer-Support Rep where to set?

I am the one responsible for our company ‘s (6storage.com) plugin (Search Results for “6storage” | WordPress.org). We have only one account on WordPress.org, I can’t seem to find where to set Owner-Committer-Support Rep roles anywhere, not by clicking on the “Advanced” link on the plugin page as advised by the help article.

Any pointers?

Many thanks for the assistance!
