How to disable “Insert worksheet “ form tab ? except “input”,”output”, and “temp”.

Dear all , i have three worksheets “input”,”output”, and “temp”. here sheet “temp” is not visible . it is being created for processing some activity and after that it deleted during run macro. I want to implement below macro code sothat no one add new sheet except “temp “sheet. below code is working fine if “temp” sheet is not created by macro . how to implement some logic sothat it can ignore the “temp” sheet .

    MsgBox "No new sheets allowed in this workbook", vbCritical, "User warning"
