I can't left-click on the icons to open the panel?

Hello, It is not functionally possible to assign the left-click action, as that button is responsible for the marker editing function on the client side.

y como hago entonces?

Select the layer you want on the left and right-click on the marker or in the list; this will open the interaction menu. You can also teleport around the map using DUCK+RMB if you have the necessary permission. What problems are you having?
