如何将 selectionMode 设置为 Unlocked？ Excel 插件，Office.js

Question

I have a small excel add-in, written in office.js and using Visual Studio 2019. Whatever I do, I can't get the add-in to protect the worksheet and allow the user to only select unlocked cells.

I've googled till my eyes bleed, best example for use is this one . This contains many options, but not the one I want!

Microsoft documentation is here .

function ProtectSheet() {
     Excel.run(function (context) {
          var sheet = context.workbook.worksheets.getItem("Sheet1");
          sheet.protection.protect(); //works fine, obviously doesn't achieve what I want

          //here's the formats I've tried:
          sheet.protection.protect({ SelectionMode: "Unlocked" });
          sheet.protection.protect({ SelectionMode: unlocked });
          sheet.protection.protect({ SelectionMode: Excel.ProtectionSelectionMode "Unlocked" });
          sheet.protection.protect({ SelectionMode: Excel.ProtectionSelectionMode unlocked });
          sheet.protection.protect({ SelectionMode?: "Unlocked" });
          sheet.protection.protect({ SelectionMode?: unlocked });
          sheet.protection.protect({ SelectionMode?: Excel.ProtectionSelectionMode "Unlocked" });
          sheet.protection.protect({ SelectionMode?: Excel.ProtectionSelectionMode unlocked });

// all of the rest just compile to sheet.protection.protect() when viewing in the debugger;

          return context.sync();
     })
}

The sheet is protected, but the option to select only unused cells is not set.

Thanks in advance!
