+Add props `helperText` and `helperIcon` to MenuItemGroup. It renders an icon with a Tooltip behind the group section title, if the menu is not collapsed. If only a `helperText` is defined the icon `QuestionMark` will be used as default. If only `helperIcon` is defined the icon will be rendered without the Tooltip.
+
+### Examples:
+**Show helper text in a tooltip with default icon:**
+```tsx
+<MenuItemGroup
+  title="Group Title"
+  helperText="Helper Text"
+>
+      {/* ... */}
+</MenuItemGroup>
+```
+**Show only a custom icon:**
+```tsx
+<MenuItemGroup
+    title="Group Title"
+    helperIcon={<QuestionMark />}
+>
+    {/* ... */}
+</MenuItemGroup>
+```
+**Show a custom icon with the helper text in a tooltip:**
+```tsx
+<MenuItemGroup
+    title="Group Title"
+    helperText="Helper Text"
+    helperIcon={<QuestionMark />}
+>
+    {/* ... */}
+</MenuItemGroup>
+```
