Check hybrid system warning after spark plug change.

So I just finished changing the spark plugs on my 2014 80k miles. I also removed the intake manifold to find it was clean and EGR ports not blocked by crud whatsoever.
I just put everything back together and turned the car on to find a yellow triangle with the message “check hybrid system, stop the vehicle in a safe place”.
I got the “ready” symbol and the cars gas engine started up as usual after a moment.
I did unplug the orange service plug before performing the aforementioned repairs.
Should I unplug my starter battery’s negative cable for 30 minutes to give it a reset?
I plugged my obd scanner in and found no codes.
And FYI I never got this “check hybrid system” message any time since I’ve owned this car the past 6+ years.

 

I was thinking it had something to do with the orange plug as well.
What are the three steps? I watched a few videos on the orange service plug and it seems that I did install it correctly.
1. Insert orange plug.
2. Flip lever down.
3. Slide lever to the side so the words “unlock” are no longer showing.

Did I miss something?

 

Update:
I let the car sit for 30 minutes or so and went back out to start it again… and the yellow triangle+check hybrid system message was no longer there.
Maybe it just needed a minute to figure things out.
