Welcome
One important thing to know (one I wish I knew sooner), for the level 2 port (the one you just used) the car controls the locking mechanism. But on the chademo port (the quick charge port) it's the charging station that controls the locking mechanism.
On your behalf, I would like to go public with the fact that I did the very same thing when I first acquired my used 2018 Leaf.
The only difference between you and me is I didn't tell anyone.
