Where is A4 - A7 on the Arduino Mini Pro?

I’m trying to setup a history graph using the A6 pin on my Arduino Pro Mini but Blynk only lists A0 - A3 in the app? Is this a mistake in the app? Does the firmware for the pro mini not support A4-A7 for some reason? I know A6 and A7 are read-only analog pins but A4 and A5 are normal GPIO.

@vshymanskyy could you please check?
