I cannot delete this organisation through Organization Management

I have multiple organisations and I want to delete this organisation but I cannot. There is no “Delete” button.

Hi,

Due to the implicit rule that 1 organization will be 1 account, you can go to Account Settings, then Delete Account. Once deleting the account My Org_01, expectedly, this org will be deleted as well while other of your orgs will be maintained. Thank you!

In other words, you cannot delete org_1 while it is open. To delete org_1 you have to switch to org_2 then delete org_1.
