TestComplete doesn't show click method on inspection but it will appear in browser

Hi rraghvani thank you for the reply. Unfortunately that button when clicked is just to produce the dropdown menu to see the further nodes. The <span> element which is the "plus" icon on the browser is what im trying to click to show a further dropdown menu. However that is the only element used to show that further dropdown menu, if you remove that <span> you can no longer access or click anywhere to get that next dropdown menu.

I have tried to use the JQuery code you suggested however it produces an error "is not a function" when i run the test. Is their a specific way of using Jquery or regular JavaScript within TestComplete?
