How to hide the queries and connection in Excel

[mrchonginhk]

I created several PowerQuery but I want to hide it.
Now, everyone clicking Data > Query and connection can find it.
How to make it "invisible" to others ?

Thanks

Review - Protect Workbook
but after that check if your result tables will work

edit:
but this is very illusory protection because they can simply copy the M-code without opening the PowerQuery Editor
this is only against changes in queries
