How can I fix a multi-level dropdown issue in Bootstrap, where submenus do not open as expected on click?

I tried making a multi-level dropdown menu in Bootstrap isn't functioning as expected. The submenu under the dropdown "Types of Massages" does not open when clicked. Here is my code:

    
History of Massages
    
Benefits of Massages
    

        Types of Massages
        

            
Item 1
            
Item 2
            
Item 3
        
    
    

I tried making a multi-level dropdown using Bootstrap 5.3.3, the first two dropdown menus open, however the third doesent open. I assume this is because Bootstrap in general doesen't support multi level dropdowns, however I am already too far in ,y project to stop and use another framework like Tailwind
