I wrote a trivia question for my team and it looks very much the same. Somone was able to get the answer by finding your blog.

So i thought i would share what we use:

saveRecord(context) {
        const saveKey = Symbol.for('saveRecord');
        /**
         * @description Netsuite native proxy for clicking the save button.
         * @returns {*} N/A.
         */
        const clickSave = () => window.getNLMultiButtonByName('multibutton_submitter').onMainButtonClick(this);
        if (window[saveKey]) return true;

        requireAsync['P:N/ui/dialog']
          .then((dialog) => dialog.confirm({ title: 'Confirm', message: 'do you want to save?' }))
          .then((answer) =>{
               Object.assign(window, { [saveKey]: answer }));
               if( answer) clickSave();
          })
           // just in case OP cancels the native no-change-prompt that can occur
          .then(()=>Object.assign(window, {[saveKey] :false}));

        return window[saveKey] !== true;
      }

• The saveRecord entry point function cannot be async (i.e. returns {Promise<boolean>} is not supported by netsuite in this case) -- as you implied
• we always return a boolean (stronger typing for code quality)
• We don't use named globals because it will pollute the namespace and our linters will bark.
• You can effectively ignore the requireAsync call -- it's just part of our rapid bootstrapping process which requires modules in a memo-ized, promise pattern (i.e fully async)
• this implementation doesn't require any external references and thus one can import it this method into their build process directly.
