Depress brake pedal and push power switch to start

I got a 2017 Lexus CT200h.

I was initially working on adding some LED lights to my car, until it appeared my battery was running low. I initially had the error "Lock malfunction when parking, park in flat place and apply parking brake securely":

So looked up and it seems like battery was low and people suggested jump starting the car.

I bought this Jump Starter battery pack from Amazon:

And tried jump starting my car:

But now I keep getting this error on my dashboard "Depress brake pedal and push power switch to start". I literally pressed the brake pedal as hard as I could, and continuing kept pushing the power button but nothing is happening.

My key fob now isn't responding to my car, I cannot lock my doors (had to manually lock the door).
Just before jump starting the car, my key fob was working perfectly fine, it can lock/unlock the car and I was able to turn the power button on.

I tried using my spare key also, doesn't lock/unlock the car. So seems like either battery is like dead? Did I jump start the car wrong? Please advice.

My car is 2017, hasn't been replaced since.
I was going to suggest replacing the 12V battery or have it tested for free at a store. That seems to be everyone's first suggestion when it's related to something electrical.

Have you tried having a shop diagnose it?
No, so if I remove battery and take it to a shop they should be able to provide me a free battery check?
I would call them before you show up. Here in the USA, you can go to an Autozone or Advance Auto, I think Walmart even, etc. (and some other local non chain shops) and they won't charge to do a battery test.
