Will leaving 2018 MBP plugged in all the time damage it?

I'm just wondering if this is okay (to leave it plugged in all the time when using an external monitor). I would assume it is, as with a Thunderbolt 3 monitor you wouldn't have a choice (as the display cable would also be providing power and charge to the Mac).

You can leave it plugged in, no problem.

Mine is plugged in all the time.. What I do every 3 months or so is deplete the battery and then charge it back up. I am no battery expert but have been told doing this will keep the battery in better shape overall...

The battery doesn't like being plugged in 24/7/365. Use it on battery every once in a while and run it down a little bit.
