To reach your organisation' settings page, you simply login and click on your initials in the top right, click organisation settings.
From here you have a few options;
View/edit your organisation details
View all team members
Invite new members (we recommend reaching to Alex for an onboarding session for all new users)
Organisation settings depend on your account role, which will either be admin or user.
If you wish to be upgraded to an Admin for your organisation, either reach out to another Admin or speak to Alex.
