Delete some of the currently invited users

[sihyoun_park]

I'm about to delete some of the users I currently invite to Confluence.
I thought I was the administrator, but when I tried to delete the users, I couldn't delete them. So I decided it wasn't the administrator.
I'm only 3 of 7 people left now and the other 4 are trying to upgrade their subscription after user cancellation.
I'm currently using a free version and I'm looking to upgrade to a standard version.
Please tell me how to delete the user.

Is it possible to remove users even if they are not administrators? (Changing access rights)

Please check and let me know. Thank you.
