Can't make calls, edit account, access account details "It says require approval"

What and how did you try to edit your sandbox account and create a call queue?

I check your sandbox account and you have only 1 main super admin extension 101 (which is you). You can login the sandbox account admin portal with the super admin 101 to add more users (up to 4 in total), add direct number to the users. Then you can create a call queue and select members. Here is the screenshot when I tested to add (not actually submit the creation) a call queue to your sandbox account, there is only 1 user so it does not make sense to test a call queue with 1 member.
