Changing dockstore username

My Dockstore username was auto-generated to be my e-mail and I am getting a prompt that I should update it to not be an email, but it won’t let me update? Can you help with this?

In order to change your username, you need to not have tools nor workflows, nor belong to any organizations. Ideally you would change your username when you first register, before you own/belong to any entities.
