We require any account admin to be able to connect their calendar (google sign-in) and currently they are NOT super admin of the account they will be using.
So I kindly request if you can enable any user to be able to connect its calendar in Calendar > Integrations, even if the user is not a super admin.
What happens now is that we (wl) are the super admin, and when any user using the platofrm tries to connect their google calendar, it doesn't allow to do so. Only super admin (we) can do that, and we can't login in their google accounts..
