How to modify create or delete Temp Group

This one works for me to also delete if it exists:

//Check if we have a group named "Temp Group"
var hasTempGroup = sf.ui.proTools.mainWindow.groupListView.childrenByRole("AXRow").allItems.map(function (row) {
    return row.children.allItems[1].children.first.title.value;
}).some(function (groupTitle) { return groupTitle.indexOf('Temp Group') >= 0; });

if (hasTempGroup) {
    //We have a temp group
    //Delete it
    sf.ui.proTools.groupsDelete({ groupName: 'Temp Group' });

}
else {
    //We don't have a Temp Group. Create one and set our preferred settings.

    //Click "New Group..." in the group list popup menu
    var groupListPopup = sf.ui.proTools.groupsOpenListPopupMenu().popupMenu;
    groupListPopup.menuClickPopupMenu({ menuPath: ['New Group...'] });

    //Wait for Create Group dialog to appear
    sf.ui.proTools.createGroupDialog.elementWaitFor();
    var dlg = sf.ui.proTools.createGroupDialog;

    //Set the name to "Temp Group"
    dlg.textFields.first.elementSetTextFieldWithAreaValue({ value: 'Temp Group' });

    //Set "Follow Globals" to false
    dlg.checkBoxes.whoseTitle.is('Follow Globals').first.checkboxSet({ targetValue: 'Disable' });

    //Choose "Attributes" page
    dlg.radioButtons.whoseTitle.is('Attributes 2 of 3').first.elementClick();

    //Check all checkboxes
    dlg.checkBoxes.allItems.forEach(function (cb) { if (cb.title.value !== "Follow Globals") cb.checkboxSet({ targetValue: 'Enable' }); });

    //Click OK
    dlg.buttons.whoseTitle.is('OK').first.elementClick();

    //Wait for dialog to close
    dlg.elementWaitFor({ waitForNoElement: true });

}
