I have a issue with my data validation; my client requests a function: fetching data from the server and filling the response into the dropdown (requiring allow multiple selections). But when I use requireValueInList to generate the dropdown, I can’t find any option to enable that. (I attached 2 images below)

const rule = SpreadsheetApp.newDataValidation()
  .requireValueInList(['Yes', 'No'], true)
  .build();
sheet.getRange(4, index + 1).setDataValidation(rule);

data validation created by app scripts

data validation created by data > data validation in menu bar
