Members
You will find your organisation on the home page so then you can go to your Organisation page as an admin.
You can see the ‘Members’ section on the top menu.
Once you click on ‘Members’, you can see all the members and admins of your organisation.
Remove Admin
From the ‘Actions’ column, click on the three dots, and choose ‘Remove Admin’.
This way, you will be able to remove yourself from being an admin.
