Bug: Menu toggled on right-click as well

Issue: Menu toggled on right-click as well

Description: Currently, the menu is being toggled on both left and right mouse clicks. This is happening due to the use of pointerup and pointerdown events. These events listen to all mouse buttons (including the right-click) and are causing the menu to toggle unexpectedly.

Steps to Reproduce:

1. Open the menu.
2. Observe the menu toggling on right-click.

Possible Solution:

1. Use click event instead of pointerup.
2. Recommended: Block the right-click within the toggleToggle function to avoid regressions:

   if (event.button === 2) {
       // do not toggle
   } else {
       // existing code to toggle menu
   }

Expected Behaviour:

• The menu should only toggle on a left-click (button 0).
• Right-click (button 2) should not trigger any toggle behavior.
