I have a MDB group select input, which I'm trying to input values programmatically, however, I'm unable to accomplish this. Please note that I used the snippet of code found below on another single select dropdown, and it works just fine. However, the issue seems to be with GROUP selects.

Expected behavior Set value programmatically for GROUP select option, NOT for multi select.

Actual behavior No change in the dropdown when I run the function.

Resources (screenshots, code snippets etc.)

                let includeSelect = mdb.Select.getOrCreateInstance(
              document.querySelector("#include_dropdown")
            );
            includeSelect.setValue(["1", "9"]);
            console.log(includeSelect);

OTHER EXAMPLE FOR WITH GOOD OUTCOME:

const domainSelectInstance = mdb.Select.getInstance(
                  document.querySelector("#domainLimit")
                );

                // Get the Domain_Limit value from the server response
                const domainLimit = data.Domain_Limit;

                // Set the value using the setValue() method
                domainSelectInstance.setValue(domainLimit);
