If your questions is as per you're title - You can do /doortarget and this usually selects the nearest clicky thing then do the command ' /click left door' to click it.
If you know the id which you can find by trial and error you can use '/nav door id 1 click' changing 1 for whatever you need, sometimes it wont work if the navmesh doesn't go all the way like if the click thing is on a wall.
Mq2Dannet will let you execute on your group by prefixxing /dgga
If you're asking about e3, it relies on some older plugins that aren't in the vv build here and so e3 wont work without editing the macro.
I'd be confident that whatever quality of life stuff that is in e3 can be surpassed by the standard vv build and plugins available here.
