I was checking the default solution in new UI, I need to check flows we have in the system. I am very new this UI and it took time for me to understand how can get the list of components by component type.
In Classic Editor, the left navigation pane helps to select the component and the canvas would show the selected component types.
If you want to check the components by component type on new UI, you have to click on small Arrow icon beside Search on right side and it provides the option to select the component type.
Hope this helps.
