Submitting needs a Discord login so we know who made it - uploads are open to community members with the Trusted role, and everything is reviewed by a human before it appears publicly.
You are logged in, but uploads are limited to members of our Discord with the Trusted role - and your account does not carry it (or is not in the server). If you think that is wrong, poke us in the Discord.
Login is not configured yet - check back soon.
